Allan, thanks for the follow up.
On reflection, it makes sense about the lack of a oem rear stabiliser bar. The mfr prob doesn't want one on there unless it would be a strong benefit for most owners (because of the application), or they demand it.
Because they are designed to reduce body roll, I like the idea of them and think it helps on our truck but could be hard to tell because ours also has extra stiff springs. I don't know much about air bags so can't comment on them.
I flipped through those links. Don't think I saw a flatbed with wheel housings/arches. Nor, from a quick scan, one constructed in a way that might be easily be altered to lower height. The base of our deck for eg is two large channel beams that sit ontop of the truck frame. They are 6" but could have been spec'd at 4" or 8" or something else any of which would have altered the deck height. I guess contacting some mfrs about your requirements could be a next step.
You mentioned the under camper platform on the previous camper. On the replacement camper is the bottom to overcab dimension the same as on the old one ? If it is now smaller it would seem that the difference would help toward the the flatbed height increase. You mentioned up to 6" - we can agree, that's a lot, especially after your experience (bad luck indeed).
I'm curious about your storage idea for extra fuel and bike. Just for fuel, how much front to back space will you need ? And the bikes, I can't get my head around that. Or are they foldable type ? Have you ruled out carrying them at the front or rear of the vehicle ?
Thom's (ntsqd) idea is an interesting one. [ON EDIT referring to post #4]. I'm thinking a small footprint, low riser frame (or flatbed) could allow for large, flexible storage space at the sides. I don't know the CA of the Tundra but wonder if it would be enough for fuel cans and/or bikes - if they were folders. Trick would be the finishing, and finding a fabricator ...
