Agree with other replies to your post in that the dealer and/or manufacturer should be given the opportunity to remedy the situation first. Another response to your post said to keep all paperwork, keep a log of all correspondence - who you talked to, when & the gist of the conversation. Be accurate. Keep a log of all the issues, and pictures to help bolster your case are a good idea. If you subscribe to Trailer Life mag take a look at the "Action Line" section (where customer disputes with dealers or manufacturers are highlighted). With very few exceptions those customers who had the dispute resolved in their favor kept meticulous records.
We purchased our TT new in 2000, and like you we discovered things that needed to be fixed, even though it was a new unit. The dealer dealt with them promptly.
One final note, as another reply to your post implied - there is no such thing as a maintenance-free RV. The owner has to be diligent, too. Good luck, enjoy, & safe travels.
