Porta Potty with a bag if we have wimmen folks that desire it or there arent any outhouses around. Its an arguement as to whom takes the baggie home though, lol. We bury the effluent there though.
SD, its pretty much a requirement now to use the air mattresses now. So much better for your back, warmer due to the air insulation from teh cold ground, and they are really compact. I also usually bring my electric blanket along and run it using an inverter from my truck if its too cold. This last time camping though my inverter was burnt out, and my truck wasnt on the road so I couldnt power it. All the trucks already had their outlets spoken for.
