I can live in my EL for a week easily, just did in Glacier actually! Youve probably seen my interior, most rear seats removed and a platform bed installed. Heres the addition i built on the side. Nice dry area out side door.

Takes up almost no space to transport , sets up and tears down in minutes. Sheds all rainwater without pooling. Noah's Tarp & Kelty adjustable collapsible tent poles. I normally tie one corner to roof rack but this was tied to tree so can drive Expy through like a garage.
Saw that post but never understood the point
Wasn't the loading floor plenty flat for a mattress or airbed anyway?
I've camped in the Expy and Navi plenty, quite comfortable as long as external temperatures are 60-90 F.... 100+ gets pretty gnarly, although you can get a nice breeze going to help if you pop the rear glass and a front window.
Deflectors are a must. So's tint. Still gonna need a hood or cap pulled over your face if it's daylight in sunny places
For temps in the 40s and 50s, wear heavy clothing. Sweats and hoodies and stuff.
For temps in the 10s and 20s.... have a full-ish tank, button her up, and run the dang heater. Oh and set an alarm so you don't run yourself out of fuel. Idle consumption was ~0.7 gal/hour iirc, but don't hold me to that and have enough for if it's twice that AND you manage to oversleep by +4 hours.
Wouldn't wanna be stuck up on a frozen mountain with an empty tank and no way down
