Lots of nice trailers that are easy too tow like, hi/lows tow light ect.Check out Trailer Life. I see you are tall that may be an issue with many smaller trailers. Custom ideas- check horse trailers alot of those people haul their horses in the back and have nice living areas in front. I've thought about a flat bed of 16' and making a self contained 10' Box that would fit like the pick-up camper you pictured. Then I would have a flat trailer and a camper! And the camper could double as a guest room. Short wheel base tow vehicle= short wheel base trailer.
