Many thanks Chris --- Looks like I have some cutting and welding to do unless I get lucky at a scrap yard.
Still having to wait on major pieces from the sheetmetal shop so I jumped back on the body and such.
Peeling many layers of paint off the driver side now. Most of the passenger side was done months ago. Aircraft stripper and a putty knife gets most of it then a few passes with a stripping pad on my grinder. Also throwing some rust converting primer on as I go.

The dark stripe down the side is where the upper rub rail was. The factory applied zero paint under both the upper and lower leaving it to rust pretty badly. No primer, no paint, nada. Nothing through on the upper, but the lower was so bad I had to make all new replacement panels for both sides. Thanks guys!

Also got back on the floor. Under the protective paper mats are a couple of layers of enamel with a lot of the magic pixie dust mixed in. No room for any more insulation than that but it should help limit any sweating. Hope to get the marine ply down soon.
Then there are all the electrical questions. Like...what the Hell am I doing!?
No idea myself and I can't seem to find anyone with broad based RV wiring savvy about multi input/multi function systems. I am wanting to set this thing up to maintain some house batteries through the following...
- A Progressive Dynamics Power Control System(Converter/Charge Controller/Breaker Panel)
- A Honda 3000 inverter genny
- A 250 amp alternator
- and, of course, Shore Power
- I "might" complicate it further with a small solar package later
I have not even been able to verify the correct wire gauge for the 120v. Online charts seem to wander between 14 & 10 for a 15 foot run. As near as I can tell, the loads I am looking at should be OK with 12/3, a sample of which I just acquired. It is a waterproof, outdoor rated wire that I hope will handle 15-20 amps for the microwave, a portable heater, possibly a water heater and a couple of wall outlets for miscellaneous stuff. All will be on separate circuits (wires) which are fine stranded...like this...
I have been trying to get in touch with someone a local company that builds custom Fire and EMS vehicles that have some very sophisticated but reliable systems similar to what I'd like to assemble but have had no luck getting someone to freelance on the side. Until I can get a better handle on how this should all go together, I am pretty much stuck for now...electrically speaking.
ONWARD-ISH ???
