One POV - to get way out there with more toys and comfort - is shown in some of the Military Trailer projects here. SERIOUS boondocking going on, with some good Interior and storage ideas to utilize. A short wheelbase, moderate-clearance TD would have made it behind a 4WD/AWD IF inertia is maintained on some gully inclines. Much of the County Road BLM is Trailer-compatible.

My 'recycled' Bedding from stuff laying around worked 'OK', but still beat the Air Mattress I've tried. Prem's idea above sho sounds mo better.
Nearer the very-civilized County Road prior going to the Escalante Stairway BLM out of Big Water UT, some old gems had served as housing for the Corral adjacent. Note the Soil composition; impassable during rain:
I saw one 'SoCal' Teardrop at Lee's Ferry Campsite on the CO River [a NICE setting via paved road], and some sharp CTs on the road w/Windows and AC units that suggested living space inside.

The 'Lost Coast' of CA looks like an interesting place, too. See it on Google Earth, which was a handy tool in planning this Lake Powell expedition. Elevation readouts, and embedded, uplinked pictures, really preview an area. In that only small Trailers are advised in certain spots on The Lost Coast, those or Truckbed Camping are good options for shaking out the cobwebs on a minimalist trip.
