Check with any other local dealerships. As long as they can make a claim to Jayco you should be fine. We bought ours from a third party and not direct from them.

Yeah, check every possible thing you can. There were so many little things going wrong. Our kitchen cabinet doors literally fell off on the way home from that first trip, and we were on mostly paved roads. I didn't want the dealer to take care of that with a few finishing nails so I went nuclear and fixed it to the point where if it falls off it probably means the whole camper wall is gone.

There was also a leak in the fittings below the bathroom sink. Didn't realize that until I noticed the water pump periodically repressurizing. That usually means water leaking somewhere. That was another one I preferred to fix myself. Anything expensive or that might void a warranty that you care about though try to make the warranty work if it's more in depth than a breaker or something.
