It sounds like you have a few candles on your cake, and might be ready to head out on adventure. GOOD!
A class C will be easy to drive in the crowded Eastern side of the U.S. They are easy to heat and cool, usually don't need lots of planning to maneuver, as good on gas as a tow vehicle and trailer, and when you arrive, you don't need to spend time outside the rig much. Our buddies have a 30 foot Winnie and it is rally nice.
The insurance will be a bit more then a pick up truck and trailer.
Come on out West and experience places that you can't see another person or building.
