A used DIY RV would be the easiest and quickest way to RV life but the coin has other side also. This Volvo B10M from 1996 would had cost something around 35000 €. It is in good condition and build and maintain with love.
Half of the living space is for a race car as the RV has been used for transporting the race car and living at the race area. But do I need a normal size car for groceries? I drive 95 % of the time by myself and no more than couple times a year there is more than two passangers in the car with me. It feels unnessesary to use half of the living space for the car. And no mather how much I love my 18 years old E class Mercedes Benz I would be happy to switch it to a Smart car and save half of the living space a full size sedan takes. I could build a sauna for that space that a Smart car leaves more for living area. Sauna!
