Every RV brand I buy I swear I'll never buy another. Problem is as I get older I'm running out of choices :)
All RVs are made sub par IMO. But what can I expect for how much they cost? Dealing with poor quality is just a way of life unless we consumers are willing to pay. And there are some manufacturers that make REALLY nice high quality stuff but you'll pay for it.
As far as what I have to offer to the OP's question, I currently own a Salem TT (made by FR) and it's been marginal. There have been the usual cheap quality things like doors falling off the hinges and whatnot. My axles and wheel bearings failed in less than a year and had to be all redone. The dealer told me it was because I let the trailer sit for too long (again, this was in less than a year so I'm not sure on that one?). The electric side of my water heater has failed twice (dealer tells me it's from using it too much?) Now, my water pump just failed after less than 3 years with pretty light use.
To me this is about what I expected for the $$ paid. Overall, it's a fun trailer and I enjoy it. The problems are just part of the routine as far as I'm concerned.
