Once you have made the decision to be a full time RVer, you are faced with the major project of downsizing from your "sticks and bricks" home to an RV. Even if you live in a modest, three bedroom, 1500 square foot home, downsizing to an RV might be overwhelming. In our case, we have a 33' motor home which gives us about 240 square feet of living space with additional storage space in the "basement" compartments.
