I pulled a lot of different trailers when I was with Watkins...most of them had seen better days but got down the road okay. Had a couple "bad trailer" stories that left me stranded or stuck waiting for service to get fixed, but you'll get that anywhere.
I had more problems with the truck honestly. 2005 Volvo 670 and it had been mishandled quite a bit by the time I got to it. They fixed a bunch of things on it but it was a losing battle trying to keep that thing "right".
