Uhaul did not stay in the camper rental business for very long is due to damage sustained by renters that had no clue how to handle a trailer. Ours had poorly repaired jackknife damage and damage to the rear from backing in to some object. We paid $1800 for ours and it needed work at that time. Auctions can generate a wide range of prices, sometimes fueled by buying frenzy and no knowledge of the item
for sale. As with any old camper, conditions can vary over a wide range. I suspect the buyer of that
Uhaul had no knowledge of all the issues they commonly have and the uniqueness of their parts, most of then no longer available
