I guess every manufacturer producers problems with some of their rv's.
It will continue as long as humans are doing the actual work and not robots that do the same repetative thing over and over. Probably most lemons are made on Monday after a wild weekend.
I had seen on some of the other forums many horror stories from the other manufacturers that make our Gulf Streams seen mild to some of the problems that I read about them.
I must say that Gulf Stream has always stepped up and taken care of anything that was needed on our coach. Even when the toilet started leaking at the Back Home Rally in June. The techs just removed our leaking toilet and installed a complete new toilet for free in our coach that is out of warranty. That's service, I really expected to have to pay something and I would have.
