Customer service lacking

I can feel for you. My experience with a new winnebago in 2001 was somewhat do similiar as yous only mine went on for 5 years until I got rid of iy. For 5 years I started and completed every trip I took at the dealer. The dealer was responsive , but sometimes had to wait for parts that took forever to arrivr. The dealer supported me to winnebago and winnebago picked my coach up in NM, took it back to the factory and returned it to me. Winnebago was still authorizing one year type warranty work at the 5 yesr point. I kept track of the mileage didicated to warranty. It was 8000 miles. I talked to every same model I found in RV parks, maybe 100, and no,one had problems like I did. I think sometimes they just produce a lemon.I solved my problem when I got a Newmar product. I feel for you, good luck.
