We buy Jayco in Tawas Michigan and have had 3 new ones from them. The first thing is they come with a 2 year warranty. The other reason is we use our trailer for 6 months or more a year. We go and go.
If you plan to be like many and only use it for 2 weeks a year then it really doesn't matter as they should stay together that long.
We currently haul a 40' TT and have had little problems with it but it is large and we don't like 5th wheels. I am sure many here can tell you the 5ers to stay away from, listen to the people that use them not just own them.
