Another thought.... since you are going to be making payments, you might want to look at a several year old diesel pusher. For example, if you were going to look at a 4 yr. old gasser, you might could look at a 6-8 yr. old diesel pusher. The diesel coach would probably be a little more upscale with real wood cabinets, etc.
Also, you won't have to sell the minivan and you will have 10,000 lbs. of towing capacity. If your van is not towable four down, a dolly might work.
You know the fine folks here at rv.net don't mind helping you spend your money.
Safe travels and good luck.
