DP is number one most expensive form of RV there is. They take lots of cash to keep operational. If you have never owned an RV before that is the last thing I would suggest. If you have not lived minimalist life style I woyld suggest trying to live in 350 square feet for a month. If you have not killed each other by then then maybe. Since RVs are a depreciating asset there is no way anyone in their right mind would consider selling a house to buy one. Just not smart.
