DB, With all the different density foams you can get these days , there's likely many ways to get what you need to get to the "overstuffed armchair smoking a cigar and drinking scotch" part ...

I got a friend that just got an Isuzu pup (diesel) and wants a lightweight camper top so he can go hunting in upper Texas... so I sent him here to see what you were doing ( the Hi Top truck shell camper rig ) ...
Cool.
FWIW, if I were doing an Isuzu P'up, haven't seen one of those in dog years either, the successor to the Chevy Luv though, pretty cool little trucks but I digress...
If I were doing a compact truck, I would build the platform to utilize the entire truck bed. I don't think there is enough width in there for a twin mattress AND an aisle.
HOWEVER... I am using a twin bed. So Twin is as small as I am willing to go.
Even before my BMI went up, my shoulders were too wide for say a Therm A Rest. If your friend can comfortably use a narrower mattress, there are cut down sizes available. I think Mike A.K.A. Crazy Quady is using a 24" wide mattress that would be perfect for a mini truck with asisle...
I just heard from my mechnaic. Minor delay due to health, should be going again and finishing up the details tomorrow or Monday.l
Quick rundown of what is / has / will be done for the truck refresh / hi topper build.
New "bulletproofed 5.4L 3V. These engines are notorious for oiling problems, sludging even when doing the factory oil change intervals etc... The new engine allegedly has been bulletproofed, oiling issues fixed including Melling hi volume oil pump etc... However I fully plan on doing oil changes back to the 1990s and earlier 3K mile recommendation instead of 7.5K miles. Plus will be running Seafoam on every 2nd oil change to clear out any potential problems.
Rancho Quicklift 2.5" level which only lifted around 2"... Sumo Spring coil boosters.
DV8 HD front bumper and winch mount.
Rugcel 12000 synthetic line winch.
Airaid CAI
K&N filter
SCT XCal 2
Magnaflow high flow cats
220 amp alternator, factory is 110. 0 ga battery, starter, and takeoff / DC to DC charging cables.
Replacement Tailgate handle with backup camera.
Aftermarket Android Auto head unit with 10" display.
Summit tubular side steps.
Blacked out headlights with full LED conversion
Blacked out LED 3rd brake light.
Blackout LED tail lights with high intensity LED reverse bulbs.
Line of fire tailgate light bar (The stop / brake / turn lights that go all the way across between tailgate and bumper.
Dechromed and raptor lined rear bumper.
Curt receiver hitch, Ford factory 7 pin trailer harness and towing package trans cooler. A.K.A. aftermarket installed towing package.
Repaired suicide door latch release cables. Typical Ford Supercab failure. They really ought to do better.
Pending a decision, but I need to repair the seat foam, and reupholster at least the drivers seat, but I don't care for the original fabric and am considering doing a leather seat upgrade. I know a bit spendy, but I will be keeping this truck as long as possible.
Now Camper rig.
Jeraco Hi Top , and it is the Hi Top that is key for me, camper shell. Not a perfect fit on my truck, but it works well enough. Home depot high density weather stripping foam to make up the gap at the tailgate where the shell is actually slightly too long by like 1/2". It was a cheap Facebook Marketplace find.
Using aluminum HVAC tape to seal up the bed gaps around the stake pockets etc... Using clear silicone sealant to seal the bottom of the bed to the front wall, It is tack welded but no butyl tape or anything like that was used from the factory.
Bedrug to even out the bottom of the truck bed. If too hard / expensive to get a bedrug, use plywood and speaker cabinet carpet.
DIY bed cabinet with storage. For MINE I ended up with the entire thing at something like 10" in order to get enough clearance for me to be able to sit and not have my head in the roof while sitting on the.
Millard tri fold 6" memory foam mattress. I could have gone with a 4" and had more storage under the bed, but I am a big guy and need the added cushion. I have tested this out and it is as comfortable as my memory foam mattress at home.
Not super well designed electrical compartment cabinet. I will likely redo this before I even think of the foamie topper build. But it has enough room for a 200 amp hour Lifepo 4 battery, all the wiring that is centralizd there, my AtemPower 40 MPPT solar charge controller / DC to DC charger.
2 sets of switch / dual USB Charger voltometer / 12V power ports. Each set is independently switched. This will allow me to run my CPAP, USB lights etc... in the camper.
Alpicool 63quart LG compressor refrigerator. This gets housed in the back seat of the supercab. I need to figure out how to route the wiring for the 12V power port as I want the power to come from the Lifepo4 not the truck battery.
Dokio 300w solar suitcase style panel set.
Ozark Trail 12x12 tarp shelter. I set this up off the back of the camper shell to provide an awning like space...
