The Uhauls originally had a orange box in the right rear which was the power converter. It was powered by 110 volt from the shore power cord which fed through a little push button breaker that was on the 110 outlet mounted at the rear of the overhead cabinet. Totally outdated system. I installed a Progressive Dynamics PD4045 converter that has modern 110 breakers and 12 volt fuses and a smart charger for the battery
. I installed a Fantastic Fan in the roof where there was a swamp cooler originally, some extra 12 volt lights
, and some more 110 outlets. EDIT: the original solar panel
was only intended to maintain the battery
while the trailers sat on the rental lot. The campers were only made for a few years starting in 1984 and were sold
off in the early 90's when Uhaul
figured out renting campers was not a good idea.
