SDD, yes that chassis was in Craigslist in San Diego for 5 weeks before I snatched it 2 weeks ago.
Indeed the van/RV is very unique although it was supposed to be a production RV by BornFree back in the 90s. Any searches in the internet about this 19ft RV returned empty :-(; anyway the inside is really clean and the solid oak cabinetry and upholstery is first class to say the least. It's an ideal 2-person travel vehicle.
MG, thanks for the ID of the conversion. I will then be able to say I have a Quigley

. The only concern I have when I swap it in is getting the caster right. Of course I could just elongate the mounting holes in the frame to allow for some adjustment.
