Car camping? I usually go backpacking nowadays, so every ounce counts. Car camping should be super luxe, in my opinion. Car camping gear is cheaper than specialized boutique manufacturer backpacking gear too. You can get everything you need in one trip to Walmart.
HUGE tent I can stand up in, with a piece of carpet for the floor, folding chairs, and a card table
cooler full of expensive beer, with block ice so it lasts all weekend
portable awning, for sittin' under, drinking the beer
three inch thick sleeping pad or futon, or a cot, and extra wide flannel lined sleeping bag..and full size pillows from home
for all seasons besides high summer, a propane heater (watch out for carbon monoxide though, keep those windows and doors unzipped, and keep it far away from bedding and tent walls...on second thought, never mind, forget the heater)
portable DVD player!
I know that stuff sounds super heavy, but I make up for it by taking a Vic Classic as my only knife..
