X2. If your rig is new, and under warranty, always try to take it to a Ford dealer for the work. Unless its an emergency try NOT to take it to an rv dealer for work on the Ford running gear or anything to do with the cab/chassie. Many already do lousey work on the rv part of a rig, and will be a hit and miss for work on the running gear.
In your area try to find a local Ford dealer that has large bays and can/will work on your class c.
