A Class B I can drive in town and that has a REAL bed?

When I was converting a Chevrolet G20 van I found a mattress company that would make any size mattress I wanted. I ordered one custom that fit my size and it worked very well for years. The cost was also very reasonable. It is very easy to construct a wood platform that folds up when not in use. Depending on the RV you buy, you should be able to remove the current bed/couch system and replace it with your custom platform and bed. I sure wouldn't give up on a B for lack of a good bed. You can make it happen.
