Do I see a bike rack on the rear, how is it attached? It looks like the one Mary's father had on the rear of his motor home years ago. First trip out it broke before they went 10 miles. Rear bike racks are a serious topic of mine, I've seen a couple break right off, had one of mine bend, and built rear receivers for bike racks on several campers. Bikes on a rear rack tend to bounce, and they have a lot of leverage hanging on a rack. I'm now on my third rack, a Swagman, that is rated for rear use. The frame on the Uhauls is not the easiest to build a receiver on. Mine has about 6000 miles on it now and seems OK. Be sure you have a good rack, securely mounted. As for leaks
on the Uhauls, I had them everywhere, windows
, roof, door hinge, marker lights
, think I finally fixed all of them.
