>>154400> Get a cap for it, a camping pad or two, to your level of comfort, and a sleeping bag.I did this once, leaving my tent at home and sleeping in the truck bed under the cap
(a one night camp out, as I had to work Saturday morning) and woke up in a greenhouse
dripping with condensation everywhere.
I'd suggest OP get a conventional tent for sleeping and a cap for his Ford Exploder to
keep his gear secure, dry and easily accessible and save himself the hassle of moving
all his stuff into and out of and back into the truck.
