Used motorhome, approx 6m, fixed bed, and space for 2 grown up kids occasionally

At that price an Adria Twin or one of it's lookalikes and a mod to front dinette bed would work, or if you prefer there is a CB version (coral compact?) If you can get a secondhand one of our van that also works with (for the odd occasion) three in rear bed and one up front.

p.s. I should note that in standard form the dinette bed is not very comfortable.
