Buying a diesel truck

[6x6in6]

No diesel shop I know of at Bow Hill.  There is one in Burlington and one in Bellingham though.
I agree with Josh on the front end alignment and the pull.  Very few working parts up front that can cause them to pull.  Does it have Toyo MT tires on it?  3rd gen Dodges are known to pull to the right with Toyo MT's for some reason....
Also, if you sent the vin to Josh, have him tell you which version of the 5.9 you have since the '04's released 2 different ones.  The early '04's had a 555TQ and the late 04's had a 610TQ engine.  Some minor changes but the biggest one was different injectors.  The early '04's get significantly better fuel economy.  The late '04's have a 3rd fuel injection event for emission purposes.

Thanks Cory Josh and everyone else. Me and Kyle just spent a bunch of time looking it over really good. Pulled some connectors and they looked fine. It does have Toyo mt's and it definitely pulls now that I drive it more and pay attention to it. Josh didn't tell me which motor but I never gave him my fax to send stuff over. The truck was built in 5/03 per the door tag. But title is an 04. Going to sleep on the situation and decide what to do. The dealer has been super cool so far for the record.

5/03 production date is going to be the early '04 model.  So you have the 305hp 555tq engine.
The engine data plate will look similar to this to confirm.  Look on the driver's side of the engine for the data plate up near the valve cover.

The later run '04 model engine data plates will look like this for the 325hp 610tg engines....
