we were in Asheville last year and at time had a fifth wheel and a one ton dully. I found it interesting getting around, truck at times wider than the lanes.
If you want to see Asheville I would suggest the Gray Line Trolley. They leave from the Asheville Convention and Visitors building near downtown. Easy access to the building from I240, large parking lot with room to park the RV.
They offer hop-on/hop-off tours. Stops all over town and you get 2 days for the price of one. We found this way to see Asheville excellent.
If you want a good camp ground send me a PM.
