Toyotamaniac

This topic is quite an interesting read. I have a project or two simmering in the background, and have recently gotten motivated on the custom camper idea. I have a 21' Sunrader, and a 21' Dolphin, which seem to handle pretty well. I like the way they handle, and have built two custom tandem axle flat-bed trucks (one 1976 RN28 w/ 11'4" flatbed, on EZ-Ryder Frame, and one custom extended 1980 2WD pickup (14' steel Flatbed frame). I like the 1979-1983 body style, with a slight preference for the 82-83 (square headlights), but the long-beds get hard to find, and life gets interesting when you are needing a long chassis. Anyhow, I've accumulated a boatload of RV fixtures, with the intention of building a customized RV. I like agree with you on the idea of the removable coach (I am thinking of a custom light steel (1.5" x 1.5" x 0.065" square tubing) frame, with fiberglassed sides, and a very low-profile Stake-bed flatbed, built on a customized chassis with ~50" stretch, by joininng front half of a 1983 frame to rear half of a 1980 frame I've been sitting on for a while. (This simplifies the driveline, as the longbed 2WD Toyotas have a 2-piece driveline stock, and each frame section has a bracket to mount a carrier bearing, and the only driveline section needing to be made is the ~50" center section. 160" wheelbase, ~16' camper behind cab, ~14' flatbed with stake sockets (which double as anchor points for the camper coach, which is 2' longer than the flatbed), with 4 camper jacks at the corners, with threaded steel sockets for mounting when needed, and a stowing area under the front part of the flatbed, just behind the cab, where the frame comes out straight, before the kick-up rise for the rear suspension. We have similar ideas, different design philosophy. I am a motor-home type, versus a motor camper type, and like the dedicated stove, refrigerator, sink, etc. I do believe that room is a good thing, and I am always itching to try out new ideas. FYI, all of the 2WD Toyota trucks have over-slung drive axles to my knowledge, with torsion arm front suspension from 1979 on. Possible mounting method for your coach, make pegs into the botom of your coach, that fit into sockets placed in the bed (round pins would work really well), then you can use clips, like a trailer-reciever pin, against a rubber bushing or spring to maintain tension. 6-12 5/8" pins with retaining clips should be adequate, or you could use tapered-end bolts with a large wing-nut and a pin slot to keep the nut from loosening when you are not wanting the coach loose. Kudos on your accomplishments, and on your ambition to accomplish things.
