I spent most of my time growing up on a mountain with no electric, running water, or phone. We were always told to bring the basics....because if we stow it, we tow it!!!

Even as kids we were responsible for our own crap! I also did the same to my own 2 children. I had them pack a back pack with just the basics. If they asked me to carry their back packs, I said "No".
So, here is what I do...
Tent Camping
tent
cooler
whatever food is in the fridge (milk, eggs, meat)
ice from the ice box (yes i am cheap)
Food from the pantry (noodles, peanut butter, bread, a few canned goods)
wood
matches
1 pair jeans
one coat
2 pair socks
1 Tank top
1 tshirt
2 pair underwear
1 long sleeve
back pack
water
sleeping bag
pillow
And cant forget the COFFEE!!!
Its the same for the camper. The only difference for the camper is a heater, a/c, and the port a potty I just bought.
Less is more!
