This weekend I'm planning on moving it up to the house so I can hook stuff up and do some testing. I know the switch at the sink is for the water pump. the Prev owner showed it to me, as the switch needs replaced.
it looks like it was originally a 3 jack camper, but was changed over to a 4 jack, all with heavy duty tripods. 3 are original Jayco ones (1000#), and the 4th is a Reico-Tital Heavy duty 2000#, though all are the same diameter. I only saw the 1000# marking, so I bought some REico-Tital 1000# extensions, but they were too small of a diameter, and a no return policy... So I bought some steel and welded up my own, which I should've just done in the first place.
When I picked up the camper, we had to have 2 guys in the back weighing the bed down to get it underneath. My truck in a 1972 K20 with a 4" lift.
