And yes.....we have a Class C! memtb
And it's possible Morewood could be referring to a Class B RV instead of a Class C, being the Mercedes Sprinter van is available in a 24ft, diesel powered Class B model.
The numbers he's quoted, 75K are average resell market for those.
New they run from 130K to 200K+ depending on options and how gullible a buyer may be.
Properly shopped, a comparable Class C, gasoline powered can come for half that price.
Lots easier to find parts and repair shops willing to deal with them when you're on the road too.
