Well, you won't be the only one in a tent... I thought of making my hauler into a camper too... but camping is part of the fun.
All I suggest is that you get a blow up mattress or cot.
Planning your meals is a big thing too... foods that can be dry stored, cans and bottled water is the way to go.
I am trying out a coolertron which I will have to plug in for an hour on my deep cycle batteries or truck and a small bbq.
