Just purchased a 2012 5500 cab and chassis. Mfg co mounted a utility box on truck. Picked up and drove back to our shop about 300mi. This truck wanders all over the road. Never had a Dodge before. Never had this problem with the Ford 5500's. Took into Dodge dealer said nothing wrong with alignment or tires. HELP !!!!

 

I don't know much about the 5500s but I'd get a second opinion.

Funny story: Dealer replaced my tie rods at 20k miles, went to Les Schwab a week later to get my tires rotated and they said "we realize your truck is almost new, but your tie rods are out of spec and need to be replaced, it's kind of strange, we know" and I said "you know what's even more strange? they were replaced last week!". So yeah, the dealer's idea of within spec might not be your idea of within spec.
