Has Anyone Used This Configuration?

Surprisingly there is a lot of usable space in the pickup bed (longbed truck) even with a fifth wheel hitch sitting there. We stay in the San Diego area for 3 months during the summer; here's what I typically carry in the bed of my truck:
4 white plastic/metal folding chairs
1 white plastic 5ft table
1 MasterBilt electric smoker
1 Mobility scooter broken down into 6 pieces
1 20ft collapse-able flag pole
Various stuff like stabilizing jacks, tripod, 5ft ladder, cases of beer/soda, leveling blocks...etc.

Plus I have a cross bed tool box

Everything is level with or below the bed rails.

Bicycles either go inside of the 5th wheel or on a bike rack at the rear.

I'm interested in full-time living and at the larger sizes the bumper-pull trailers seem to have a more limited selection of layouts. For example, I toured a fifth wheel at an RV show that had a second bedroom and above it was also a loft. It was an impressive (and large and expensive) layout. I haven't seen one of those in a bumper-pull, but maybe they are out there. Bumper-pull trailers also seem to be more limited in which ones have a W/D hookup, although I have seen a few with that feature. I think I've also seen a few fifth wheels with ceiling fans, but not bumper-pull trailers (except a few park models which is bigger than I want).

It may be more difficult but certainly not a challenge. There is still only one pivot point. The connection between the truck and dolly is a solid 3 point connection.

Is it legal in Texas? Other states where you travel?
