Thanks to toban for the great shot of camp and The Ghost under the stars!
The ghost gets to huddle down in the sub freezing temps and put on a snow blanket.
Fortunately all drained of water and hopefully surviving.
More updates soon!
Although most of this system has been changed/removed/modified on The Ghost, I thought the documentation from the day is fairly interesting memorabilia. The control panel with “Therm-O-Matic” is still up at the drivers position and turns on/off the blower for the heating unit. The vents above the front headsign have been blocked off and the front foot vents have been removed.
These heat channels where the air flowed above the windows were the favorite hiding grounds for the rats/mice that inhabited the bus throughout it’s past. I have removed them through the galley in preparation for proper galley shelves. This has also been removed in the bedroom area as the engine heat supplied ventilation channels are not needed back there. I still ponder the idea of removing the factory ceiling mounted heater core in favor for some more headroom in the drivers position. We’ll see if I ever cross that bridge.
I wanted to throw up some photos from our Alvord Desert trip over Memorial weekend. Bob and Merran invited us and any folks that wanted to join down for their usual landsailing/camping trip out on the playa. Emily had been to this area prior but no landsailing or camping out on the open playa. This would be my first visit to this area of Oregon for a campout.
We departed Milwaukie at a leisurely pace, leaving Thursday AM rather than Wednesday PM late. Some minor murphy moments with the grey water tank and some finishing touches on the various systems meant a good bright-and-early departure would be better advised. I tidied up the temporary 24V system (directly charged from the solar panels) and connected the converter to 12V (which we would later end up using to power the bus for our entire trip home!). A quick load check of all roof items meant we were good to depart. The trip down was mostly uneventful. We stopped an fueled the coach near Burns, OR after having a nice stop by some local county law enforcement, concerned that we were trafficking large quantities of drugs. Their search turned up nil (of course) and after learning of my Search and Rescue affiliation, realized they were barking up the wrong tree. My 65MPH in a 55MPH zone was not even mentioned once they made it clear it was their probable cause for stopping us. We parted ways on good terms, with a warning that the wind on the upcoming roads would present a challenge.
We hit the playa an hour and change before dark, right about as the sun disappeared behind the steens mountains. Kelly arrived in his newly acquired school bus just before us and we made a caravan down to the playa with Bob and Merran leading the way.
The solar panels gave us enough power that combined with a proper sized inverter from Eric, and some cables from Kelly, we ran the ice machine, radio, and lights without worry.
Some photos (credit to Kelly for a couple of his!):
The trip home was uneventful, but not without an interesting twist. Our dual-field regulator for the 100A generator original to The Ghost decided that 16.5V was better than the factory 14.2V charge rate. This, being extremely hard on batteries, led to me to disable the regulator for the entire drive home. We departed in the late morning/early afternoon, stopped by fields for a milkshake and a hamburger, and continued on. We stopped in Bend along the way to enjoy a campground for the evening and to break up the trip. We decompressed, watched some programs on the laptop, played with Marley, and got to talk with some folks in the campground. A nice solar powered showerhouse gave us some much needed cleaning, although the light electrocution from the shower console was not appreciated. We departed in the morning (with a nice solar charge on the 12V starting batteries) and headed home.
In the mad-rush to get things finished for a trip out the Alvord Desert this week, I was able to get the front rack of The Ghost finished and some new solar panels mounted. I scored a sweet deal on craigslist for some 60-cell (28-32V nominal) These are 250W 5’5″ x 3’3″, aluminium frame panels constructed for home power installation. I built under-supporting frames to help bear vibration load since the frames are not designed for mobile applications.
I started by extending the existing rack I built last year farther forward to support the panels. I constructed it out of materials and in such a way that it is actually rated to support humans. The wind load of the panels could be quite substantial in high winds or at high speeds.
Once the rack was finished, I welded some extra support pieces onto the spreaders to support the panels in their odd locations. I had to choose this odd layout to allow the roof vent to open (power vent lid) and also not hang over the side of the coach too far or cover the horn/antennas/etc. This configuration allows me to see the edge of the panel in my drivers side mirror and is still inboard of the two air-conditioning units.
The panels are mounted at four points each using 8 self-tapping screws into the main frame members. The other side of these brackets are welded to the rack-frame of the coach. This seems to be providing a very stout level of connection and hopefully will give the panels the longest life.
The two panels are connected in parallel and directly feed a 20A 12/24V charge controller. This power is then fed into the temporary 24V sealed lead acid battery bank which is either used directly (for 24V appliances and later the large inverter) or indirectly though a 24V to 12V 360W converter. With this amount of solar combined with our desired eventual inverter/battery bank, we could actually run a small amount of solar powered air-conditioning for the morning hours while we wanted to sleep at events like BurningMan, etc. Realistically in Oregon the amount of power generated is not significant in comparison to the cost of power from a utility, however in the desert or off-grid this starts to be a large win. My intention is to eventually augment the DC power system with a 24V 150A+ alternator/propane generator combination. I have a ~30gal propane tank slated to be installed into the coach as well which will supply fuel to the stove/oven as well as the generator.
Check back soon for more updates!
Hello again! Recently the service brake valve (a D1) that I rebuilt many moons ago started leaking again. Due to the age of the valve, the age of the rebuild kit, and the general lack of available parts for such an item on the open road, I decided it was time for some changes. While plugging around under the bus, I found that there was some equipment (from the city transit days) that was also leaking. This valve (all torn apart on the bench) was the culprit:
It took some heavy researching to figure out what this valve did. It was installed between the main air-brake service tank and the foot valve in the main pressure line. It also received signals from ‘somewhere’ that I could not find the other end of. The other side of this same “unknown” line went off into a dual input check valve in the rear brake circuit. As much as I boggled my mind (and hit the books) I could not figure out why you would want to interrupt the brake signal. Finally I did some poking around in my New Look book (which I ended up with for $10 off ebay) and found that it was an emergency brake valve (before spring brakes existed). The purpose of this valve was that if there was a massive leak at the foot valve, a small hand-valve at the operators left could be thrown into “emergency mode” which applied air to this valve, closing off air supply to the foot valve. Then, this same signal was sent to the 2-way check valve for the rear brakes, applying the brakes fully and (hopefully) stopping the coach. Crude and rude, but I’m sure it did work (yet was probably never used). It still required air in the main tanks, something that spring brakes do not require (absence of air applies the brakes in an emergency). So, out came the valve, but I was left with a bunch of air-lines to cap/patch/re-connect.
The next step was to re-connect the service brake pressure line. Of course this was originally heavy gauge copper tubing (at some expense!) but the popular choice is plastic air-brake rated tubing and compression fittings. Removing the old copper line was a real chore (almost too stiff to bend, and grommets installed where it passed through the frame members. I disturbed a LOT of dirt. I out-fitted both ends (valve and tank) with the proper ends and installed a piece of blue 1/2 line.
I needed to reconnect the air brake signal line to the rear brakes once the 2-way check valve was removed. I did some fancy footwork with some fittings and gently bent the copper line to make the connection. You cannot kink this material or it will leak and a leak at this junction would be VERY dangerous.
Next on the slab was replacing the service brake foot valve up front with the new E3 I purchased of e-bay. Newer valves than this have multiple inputs however The Ghost only has a single supply air-tank system (even though it is two tanks, they are tied together, one wet, one dry). The E3 is a close replacement to the D1 and is available at most heavy truck parts places so it was an easy choice. Earlier valves in the D series have the potential for being set up for city bus service, and thus do not give the operator the option of 100% air brake power (injury to passengers a large possibility without seatbelts). Modern day with modern tires/non-commercial driving means I want the aggressive brakes if I need them.
I purchased a new E3 valve as well as a new treadle + plate assembly off of e-bay (the E series bolt pattern/size is FAR different from the D series). This required welding up the old hole in the floor so that it could be drilled for the new bolt pattern/etc.
Once this plate was installed, the center hole and mounting holes could be drilled. The E3 valve was set up with the proper fittings in the proper directions to allow for existing brake line connections. I also added a supply line to go directly to my spring-brake emergency valve as well as an application pressure port to go directly to the dual-needle gauge in my dash.
I then mounted the plate (after removing the treadle) directly through the coach body down into the E3 valve. Holes are misaligned here because I left ‘wiggle-room’ in all mounting holes to assist in fine alignment.
Lastly I reattached the pedal assembly and installed some 5/16 bolts in the outside perimeter to assist in keeping things tight.
We will see how the new brake valve feels on the road…however so far it is looking fairly promising. The high angle of this pedal assembly can be adjusted with some lathe work on the back-roller however I may keep it like this. Getting full 100% application before was a bit tricky (usually required me to toe-into the pedal). Considering the light amount of driving that The Ghost gets these days, I suspect this pedal assembly will outlast the rest of the coach.
I recently addressed the long outstanding issue of The Ghost’s corroded battery tray and dying group 8D battery. The original battery holder was rusted and since it interfered with my black water tank outlet, I had hacked on it heavily to make things work. Two burning-mans later, I decided it was time to properly build a tray to hold some new batteries!
The trickiest bit is that not only must the tray hold the batteries, they must also be removable AND allow for the plumbing to route around them (grey water from fore, black water from aft). Having the hose connection behind this door saves having to cut another door or having plumbing hanging down dangerously low on the chassis to snag on stuff. Originally The Ghost had two group 8D batteries to support the stop/go driving…numerous incandescent lights…and electrics for the door controls/starter/etc. Now that the load is lightened and space is premium, I decided to install two new group 4D batteries that I acquired cheaply (they were blemished and repaired). I normally would prefer one larger battery over paralleled dual batteries but the space only allows for maximally two 4D.
With the old battery carrier removed (held in by bailing wire), I drafted up an idea in my head, purchased a 20ft stick of 1/4″ 2″ steel angle iron and set out to building the tray.
After much cutting/tacking/getting wet and shocking myself, I finally had something tacked together ready for final welding (and it fit like a glove between the frame rails and cleared the sewage tank fitting nicely). Bottom views:
Once everything was welded up and checked for fitment, I blew on some rustoleum brown primer paint and drilled the various holes for mounting. I used fine thread 1/2 stainless bolts/nuts/washers/lockwashers to make sure things didn’t move. In once place I had to use a small spacer to make up the gap difference but in the end it was a perfect fit. On the last hole I killed my Milwaukie 1/2 drill bit (sheared it off laterally) in the frame of The Ghost. THICK STUFF!
Now it was time to upgrade the battery cables, install some rubber mat, and test fit the batteries/etc.
Once all the cables were clean/coated with copper shield/tightened I was ready for the batteries.
I obviously need to finish the final securing method to keep the batteries in their tray but the 2×4 is doing the job nicely for now. The temporary red/black duplex wire on the left is the connection to the float charger/house electricals to keep things fresh for solid starting. In the above photo you can see that the batteries are high enough to allow for the 1.5″ grey water plumbing to run under them and across to the front of the coach where the grey water tank will be. The angle piece of the front is simply for structural support and gives me a nice place to mount my battery restraint.
Check back soon for more updates! Thanks for stopping by!
The Ghost has been sitting quietly in the driveway these past couple months enjoying some much needed rest. The return trip from BurningMan 2012 was uneventful although VERY long (multiple construction zones stopped us many times, and we didn’t hit pavement until closer to noon departing BRC). I think we rolled into PDX right around 0230. I don’t like pushing it that hard, but I had a good amount of pre-trip rest stored up to tap into. The ghost never missed a beat and once we got back down under 500ft elevations, it was coming on night so the air cooled off and the horsepower really jumped up to make the I-5 stretch rather speedy.
I took her out last weekend to go service the black water tank (had been sitting in the driveway since early September) and blow the cobwebs out. Unfortunately I once again plugged up a fuel dip tube in the tank so I need to fix that (again). There must be more junk floating around in the tank causing issues. Shy of that annoyance, the rest of the trip was uneventful.
When I brought her back into the parking slot and shut things down, it turns out that some small air leak has reared it’s head under the chassis. Some quick investigation shows it right off the main dry air tank feed line to the brakes in some odd little aluminum block. I will investigate further and either a) repair the block or b) find that it’s other lines run nowhere and it can be replaced with a straight coupling. Half the air line leaks on the coach have been repaired by just removing unused fittings/lines (which used to run air doors, etc.) Otherwise, the only other concerning leak is some small one on the drivers side rear air suspension . To keep things ‘level’ I have to keep her attached to my air compressor for a weekly fill-up of the aux tank.
Next on the list is getting the two new Group 4D batteries installed for hopefully better cold weather starts and also getting the hydronic heating system installed for the early February camp-out we always attend. I usually use a 120V 1500W oil radiator heater but it’d be nice to at least have the system functioning for a full-on test. Roof painting is on hold until the weather becomes more agreeable. I am also going to start working on the coach HVAC control circuity (thermostat that will control two zones of both heat and AC)
I’ve also been slowly bringing the deep cycle batteries up to full charge that I scored out of the old paper mill. The appear to be holding charge nicely and the internal impedance is looking nice and low so far. I will start load testing them soon to see what happens. I have a holder for about 400-500A/hr of these at 24V to run the future desired inverter/charger & onboard systems (the coach itself is 12V).
More to come soon and hopefully some more interior shots as I build it out more and get it all cleaned up.
Some quick photos of the inside and current build state before Burning Man 2012.
I am right in the middle of finishing out the bathroom enough to have a decent shower space so that plus the kitchen sink area is a bit under construction…

After last year’s desert excursion (Burning Man 2011) and with our recent visit to 4th of Juplaya (2012), we decided that window tinting was now upgraded to a MUST HAVE to be able to survive in a metal tube (with glass windows) in the desert.
I picked up some ‘somewhat’ reasonably reviewed Gilla window tinting from Lowes (similar price to Amazon) and while it isn’t rated for automotive applications, should work nicely on the RV application. It is an actual adhesive (not static cling) and installs just like it would on a car (soapy solution + plastic knife). The results have been quite decent for single pane glass. I first did a rear bedroom window (directly facing into the sun) and it made a 10-12 degree F difference in surface temperature (on the white mattress). The glass had a slightly higher temperature but when viewing from the outside, it is obvious that the tint/thermal management film is doing it’s job (good rejection).
This, combined with the white painting that is happening, should DRASTICALLY improve interior temperatures of the coach in the summer heat in the desert. We don’t often open the windows at Burning Man (bad dust) so having them closed with this film should help the situation. I’m hoping it will be decent enough for us to not need to run our solar reflectors (silver bubble wrap) inside the windows as well but we shall see. The overall ‘tint’ of the windows isn’t that substantial however the reflective rejection properties are pretty decent.
For your consideration, tinted on the left, non-tinted on the right. Noticeable difference. I haven’t tinted the upper smaller windows yet.
I should have the rest finished off in the next couple nights!
Thanks for checkin’ in!
