I've got a built-in stealthy cargo box that levels out the cargo with the rear seats, similar to @Antman 's original build. On top of that, I run a 31" wide trifold mattress (honestly the same one I sleep on nightly in the house):

On top of that, a 39" wide 40ºF Coleman sleeping bag:

It's a wide sleeping setup and has the advantage of being able to sit up straight without my head bumping the roof. I prop a couple of pillows against the passenger seat and can hang out and read or work on the laptop just fine.





Also in that shot is the hot water tank and sprayer nozzle. Great for showering, doing dishes, spraying off the dust on the rear bumper, spraying kids in the neighborhood...

As for lighting, I had a buddy install an always-on USB plug into the liftgate, which I run a string of led lights out of:

Amazon.com: Luminoodle Color - 10ft RGB LED Rope Lights - 14 Color Options, Remote Control, Dimmer - 450 Lumens of Light for Camping, Hiking, Safety - Color LED String Light That Doubles as an LED Lantern: Home Improvement



The led kit has built-in magnets which allow it to be mounted inside/outside in about 30 seconds. Also has amber settings to keep the bugs at bay.

Beyond that, the cargo storage holds a 2-burner propane stove and we tucked a black 4" PVC pipe that holds 3 1lb propane tanks secured with spiderclamps under the right rocker. I don't know a damn things about propane or propane accessories and I'd prefer the stuff be outside, especially with the interior temperature hitting 130F+ in the summers here in the desert.



I'm trying to go as far STEALTH as possible, without the inside getting cluttered with storage bins/bags/coolers/random shit. Being able to roll into any random parking lot and not get flagged as a camper is high on my priority list, so even Yakima/Thule roof boxes are suspect. I'd love to see how others have tackled this.

Cheers!
