How many have bought a new class C within the last year? If you haven't already done so, get your front end aligned as soon as possible. I didn't realize mine was out of alignment until I discovered the inside tread on my Michelins was cupped and worn out in just 15,000 miles. I had noticed some vibration on the steering wheel and some handling problems.
I found out the cutaways are aligned perfectly at the factory, but when the chassis is built out, another alignment is necessary. In my case this was not done. I had the Ford Commercial Truck dealer do a proper alignment ($255.00) and mount and balance 2 new Michelins.
By the way when I asked my RV dealer about this, they seemed to play dumb saying they don't do alignments.
So a word to the wise, get an alignment done (but not at the RV dealer).
