How big could I build on a 4x6 trailer? Am thinking at least 5x8 if I build over wheels. Could I go 6.5 x 8? Here's the deal. If I buy a trailer & build what I think I really want, it would take more time & cash outlay than I want right now with our myriad home repair/improvement items going on. And I've got all these ideas about what I think I want but am not sure what is really going to be the more practical to build or practical for use.
My bro-in-law has a little 4x6 trailer he rarely uses since switching occupations. Asked him & he will let me borrow it occasionally. So I thought why not try building a little foamie on a removable platform that we could bolt onto his trailer. Then I could borrow the trailer, bolt the foamie on & off we'd go. Is this crazy? If bro-in-law would let me keep it at my house then the add/remove process could be less often, assuming he really isn't using it much any more. My incentive to him would be to let him borrow my camper. He's been wanting one.
Also, later when I get my own trailer for the project I'd originally envisioned, I could just make the originally foamie available to bro-in-law whenever he wanted or perhaps even just give it to him.
