I would hate to sell my camper and be without - and so understand how you must feel.
Even though we love our camper with no plans to sell, we went to the RV show in Puyallup, WA yesterday. Our ten year plan, though hazy, is to prepare and educate ourselves for the day when a Truck Camper may not be suitable for us.
We like the Class A's for two reasons:
1) The driver sits above the crash level (in the event of a collision with an automobile - a mac truck, no.)
2) There is a lot of wasted space in the Class C cabover construction design.
Strangely, out of hundreds of RV products, the show had no Class B's.
Best of luck to you in your search for a replacement RV.
