Camping World Service problems

I purchased a new Jayco TT from our local Camping World 3 months ago and have had nothing but problems with their service department. I just picked it up today after they have had it for over a month, just to fix some warped paneling in the bathroom and a leaking window. Had one excuse after another every week when I would call to see if these 2 minor problems were completed. After getting home and having time to really look, they didn't fix either one, after keeping it all that time. They also tried to send me down the road with the hitch half-way off the ball and tires with half the recommended air pressure. My question is "Do I have to go there in order to use the 2 year Jayco factory warrany?" I would love to go somewhere, anywhere else for future problems and to get the current ones fixed that they didn't handle.
