You would have to work really hard at it to overload a 20/21' box front bedroom TT that has a specified / designed cargo capacity of 2214 lbs. Maybe he loaded a cube of bricks on the bed? My CC on our Roo which is basically the same physical size is only 1400 and change. Even with the 2nd water tank I added I am not close to it, so I don't know how you can get a ton of stuff in that 233RBS.....waterbed possibly?
Maybe the frost heaved road was more like driving it off a 5' high retaining wall?
I sure would like to know the wall thickness of that tube.
"Wonder if anyone else is suspicious of the rust on the weld areas on both sides."
Not really as Lippert welds always look like that......Your pic of the area that bent sure eliminates any doubt that Lippert does some prep and doesn't paint over rust. That is unless you have been towing it around for a couple of months with the bent A frame.
OP..........You didn't have a bike rack attached to your rear bumper did you?
