Been a while since I updated this. Last month I spent a solid week working late nights on the interior to get it ready(ish) for a big trip. So far I have an insulated floor platform, a cabinet against the back wall, and one on the passenger side wheel well. The electrical system is contained in the back cabinet, and the diesel heater is in the side cabinet. I ran the intake and exhaust for the diesel heater out holes in the wheel well. Fuel tank is temporarily mounted inside. Long term I want to put it in a pelican case mounted to the outside of the camper.
A couple weeks ago we took it on its first maiden trip (leaving town at 10pm after finishing the last couple things I wanted to get done). We drove from Oregon, to Utah, Mammoth, then back north. There's a few issues to work out, like the vinyl strip I used to make a drip edge likes to curl up in the front from the air hitting it while driving, which then exposes the gap between the roof and camper, and rendering it useless. Luckily the whole trip was dry, so no leaks. The electrical system still needs more interior lights and phone charging outlets added, but the heater and fan worked great. All in all, I'm really pleased with it. Feels pretty luxurious to be able to sleep on a memory foam mattress pretty much anywhere we can park.
