Wont hurt to put some sort of protectant on the plastic parts. 303 aero space protectant seems to be very popular.
As for wax? Mcguires Rv/Maring is some good stuff. I just got my first can of Collonite Fleet Wax. Only did one small test piece, but from that the results look pretty spectacular.
Me? Couple of hours. DW? Couple of days. Of course, if we left with just my preparations, we'd be missing a few important items and a lot of desired items. I'd make do, but that's not an option ;).
It is an "all-weather package" for RVing along the Canadian River in the OP's state.
Ones for export "up here" will have the separate beer fridge and a rack of moose antlers on the front cap instead of the longhorns.

Ya got that right, eh! ;)
Most marine fridges are compressor operated on 12V or 120VAC. I'm sure you could find one to fit if you don't require propane operation. The fridge in our bayliner will easily last 4 days on 12V.
on how many batteries?
That would be 2-105AH deep cycle
