I've been avoiding this thread to keep from testing fate.... I've been RVing for about 15 years and have been VERY lucky. Anyone who tries to pass of the lack of damage as skill is either superhuman or a BS artist. Here are some close calls with only minor damage that could have been a LOT worse:
Backed my old TT into my gutter - I saw it and hit the brakes right at the point of impact and put a gutter spike sized hole in the fiberglass trailer shell. Filled the hole and moved on.
Backed over a sawhorse while backing my TT and stopped just before hitting the fence and gate. If not for hearing the cracking of the sawhorse I may have kept moving into the fence.
Bringing home a new 5th wheel in a rain storm and in the dark I hadn't completely figured out the swing on the 5th with respect to my tailgate. I took a chunk out of the plastic cap on my gate and damaged the gate slightly. The handle and camera now is pushed out 1/4" or so. I fixed the plastic cap of the gate and am just living with the gap around the handle.
Again, I've been VERY lucky and by all right should have done something expensive by now. I'm extremely hopeful of being able to report the same track record this fall
Happy Camping everyone!
