hey guys, thanks for the replies! sourcing info on the individual appliances, looks as though that will suffice to get the info im needing! simple solution that didnt cross my mind. thanks gdetrailer! there was a bit of shotty remodeling i've been removing over the last couple days. removed the queen size bed and shotty frame and discovered a small compressor. the copper line on it had been cut and the wires had been as well. i assume from its location at the water tank, that it is a part of the tank but not sure of how it worked. i havent seen an inverter, must've been removed some time ago. the wiring was redone as well so there is no way to hook up to a 12v source. so, do i need the compressor operating or is it unnecessary? also, the hot water heater has no identifying labels or such.is it possible to learn how it works by comparing one similar? i took more pics last night, will post shortly. thanks again guys! nice camper jim, i believe mine may be same year as yours just a different floorplan. i could be wrong of the year of mine. i found one like it and thus thats where i got my year from.
