Actually did some work on the camper. I've decided to spray foam insulate it. I waited a while to see if anything leaked; it doesn't. Fixed some old stuff, did a bunch of wiring and got the diesel heater plumbed and wired. I had to create some bulkheads to get the hot air from outside the camper to the inside. I'm probably going to have to make something sturdier out of steel or aluminum. My heater has 4 outputs. Three are going into the camper and I'm going to fabricate a removable 4th piece that will go in the sliding back window. That will keep the cab (and the house batteries) warm when it's really cold.
I have a whole bunch of cut off switches and others to switch from alternator charging to solar. I have remotes run into the camper for the heater and controller. I located the switches so that I can open the escape hatch and reach into the cab to shut things down in an emergency. The charge controller has to be disconnected from the panels before shutting down power so I needed a master switch for the panels and the battery feed. The instructions say you should run a fuse inline, but that makes no sense. If something trips the fuse, you will have solar going into the unit with no battery input?!? Still tons more to do. I need to fabricate a stand for the fridge, get new batteries and then install the water tank, plumb it and make a spot for the sink.
