Not a Runaway owner myself but I find them fascinating. I belong to an owner's group on Facebook and have seen some pretty clever things done with the interior, can't post the pictures directly here since the group is closed but for those interested here's the link: https://www.facebook.com/groups/RunawayCamperOwners/
Last month the company introduced a model that is tall enough to stand up in, the other two options are 4x8 and 6x8 and sitting room only. I'd call traveling in it "camping" over "RVing", but the benefit of that bare interior is you can customize it to have everything you want and nothing you don't, and you can always use a cot and plastic bins and such to get started with and upgrade as you go.
