We bought our unit with 3,200 miles on the clock and Thor's warranty gone. I paid less than $100 for the front end alignment and it never occurred to me it could have been covered.
My mechanic at the big truck frame/suspension shop where I went said alignment and proper tire inflation should always be the first step. He also said you should not have to keep getting it aligned every couple years. His suggestion was maybe every 5 years right after replacing tires.
