I had the guy that run a good RV repair shop to inspect my second one. He pointed out the items needing fixed, I bought it, he did the work and I never had any problem with the items he fixed. I had other issues, with wandering but nothing he had repaired.
The third we bought, took it back to the same guy, he had it forever. He takes on to much work, and it even got broken into while there. It aggravated me but not one bit of the work he has done has been a problem. The only issue I see with him is taking on more work then he can do.
I bought the second through PPL and would recommend them and the inspection guy, they are in Houston.
