They had everything we could’ve possibly needed for the camping trip; other than bedding, each vehicle they rent out is equipped with a full kitchen (propane grill, cutlery, cookware, electric fridge), camping chairs, camping table and either a rooftop tent or trailer.
You’ll still need your sleeping bag if you’re doing Jeep camping, since the top popup tent is still just that – a tent.
It’s higher off the ground and has one hardshell side, so you’ll be slightly warmer than sleeping on the ground, but you’ll still need a warm sleeping bag if you’re going up into the mountains.
Sleeping in the tent can get cold since it’s not very well insulated, but with a proper sleeping bag you could extend your camping season into late fall or even winter.
