Insulation: foamy boards

I’m picking up 45 panels of this stuff today, exciting.

Add to that some plywood panels for the floor above the insulation, and a bunch of 1″ thick boards for walls. I was thinking 1/2″ ply.

Oh yeah, I probably will run 2×4’s along the floor to support the plywood and prevent crushing of the foam.

Folllowed up with 30 of these on the walls and ceiling, to make a thermal break over the ribs:

The springs are barely sagging.

Interior Primer

Condensation has been a pretty huge thing inside as it has gotten colder. I needed to get that bare steel covered asap. I de-greased and scotch brite scuffed the steel, wax and grease removal then shot a gallon of rustoleum brown primer. It was a nice hot October, so it dried well.

You can see a photo of the sheen difference where I globbed it on extra thick on all the seams. The flash makes it look like I didn’t spray.

A photo of the door seals. I pressure washed the remaining reflective tape adhesive today in prep for sanding and painting the skirt and cargo doors, no water made it in which was nice to see.

LED Tail Lights

Having fun with the new LED tail lights. It feels like slow moving lately due to waiting for certain parts.

The weather has been pretty wet the last week so not a lot of outside work. That engine door makes a great umbrella though.

Once all the lighting is complete and its legal to drive again, I’ll be taking the bus to the big box store and acquiring a lot of foam, plywood, and board strips for the interior.

A shot with the engine door open, shows the red hazard lights inside the engine bay. Coincidentally, the outside flashers point up, illuminating the entire rear of the bus when that door is open.

Picture of the new license plate lamps.

Got the exit doors painted tonight while the weather was cooperative. Now tomorrow I can install new door gaskets, getting a little closer to keeping the weather out enough to work inside.

Stress Paint

Its stressful painting so late in the year. Got the rear done good enough.

I never knew school busses had aluminum engine lids? It was fun filling the old holes.

Thinking about the next steps

So, after the exterior is properly prepared to resist the elements this winter, I’ll of course be working on the interior. My thoughts were to first get the insulation installed, followed by walls and a proper floor. Then eventually a few windows.For example, I plan on adding significant solar capability to the vehicle in the future via large monocrystaline panels on the roof (the kind that can curve). I’ve been researching generators and their costs for an effective unit, and it seems like a much better idea to adapt a boondocking approach with a follow up of plug into a power panel. All these items mean a lot of cash, so I’m looking at a modular approach where possible.

Here’s a list of all the big dollar items I can think of right now.

  • Significant battery bank to draw from, probably two 24 volt banks of t-105 batteries, for 8 batteries in total
  • battery monitoring and watering system
  • inverter system
  • solar charge system
  • diesel furnace
  • split 48 volt aircon system
  • additional 48 volt alternator for maintaining banks when engine running
  • ~10x 100 watt panels on roof, for up to 500 watts per battery bank capacity
  • small auxiliary generator, such as the 2000 watt honda inverter generator (I wish they made a diesel version!)
  • chest fridge
  • water tanks
  • propane tank(s)?
  • composting toilet
  • cooking aparatus (induction stovetop? propane range?)To start with, I’d like to just plan on a 50 amp electrical service that needs to be plugged in. Literally some electric space heaters and a 12 volt led based illumination system.As budget and time permits, I’d fill in the other components of the “master plan”. By building with the steel frame construction and pre-allocating space for equipment, I think I can work around the major problems or refitting components later.

    Anyway, just sort of thinking out loud.

Henry’s Solarflex 287 Elastomeric Roof Coating

I took a gamble and added a layer of solarflex 287 to the roof in early October.

The directions say not to apply if there is a chance of dew within 48 hours, so I have no idea why they would bother selling it in Washington state.

Anyway, it is 82 out today and while the days are shorter we are supposed to have dry weather until Friday.

Hopefully tomorrow it hasn’t turned into a big runny mess. I’ve read some stories about it doing that.

Its currently 3:30 pm so a few more hours of direct sunlight.
