On my old travel trailer I had a similar setup, and after a 3 hour drive I noticed the bumper was starting to twist. I had a welder add some extra steel to strengthen things. I can imagine enough bouncing could cause the bumper welds to break.
I suspect a bike rack connected to a Solera experiences much less pounding than connected to a TT - which essentially has little to no suspension.
We owned TT's for years, and I only found one bike rack that would stand up to the beating of a TT - all the rest broke in a year or less. Look to the Saris "Thelma" - the best rack I have ever used, and stands up to a beating. I have owned one now for 7-8 years, and used it maybe 100 times already. Very light, very strong, bikes don't "touch", and easy to use.
