At your ages you need to buy a less expensive home and both get full time jobs to build up some savings. An RV of any kind will NEVER appreciate in value so when the time comes you can no longer live in it due to health issues (and they may not make the best home if you are disabled or sick)you have nothing with which to buy a new home. At 61 even if you both stay healthy you will most likely need to replace your RV over your lifetime more than once. Where will those funds come from? The RV lifestyle is not necessarily less expensive than living in a sticks and bricks home. If you have never traveled in an RV you might try renting one for a month and see if you can stand each other at the end of that time. It would be expensive but not as expensive as purchasing something you find you have no taste for.
