I camp with kids a lot. Keep it simple and clean. Kids love sitting in a tent and just hanging but don't let them eat or have drinks other than water in there. Also, make sure each of them has a duffle or pack and make sure they keep all their stuff in it neatly. They will trash a tent very quickly. Shoes come off before they come in. Here's my list:
- tent - I have a pretty big Coleman that I can fit 2 queensize airmattresses in. I have 3 kids, 2 girls are on one and the boy and I are on the other. The wife doesn't camp much.
- tarp footprint for tent
- 2 Coleman air mattresses in a large duffle with coleman D-Cell powered air pump. Make sure and pump the air out when breaking camp so they will fold nice
- weather appropriate sleeping bags and/or blankets
- Coleman white gas stove with stand
- Coleman rechargeable LED and Fluorescent lantern
- Camp box (plastic tote) that holds utensils and cooking pots plus non-refrigerated food
- Utensils - spatula, big metal spoon, large knife, forks, spoons, knives, plates, bowls
- iron skillet
- medium pot
- gallon size baggies
- paper towels
- brillo pads
- dish soap
- coffee pot and cups
- flashlights and extra batteries
- parachute cord
- folding table
- camp chairs
- tarp or instant canopy
- The PETT (thepett.com) - Portable toilet and enclosure - this is a must (especially for girls) if you are camping at a place that uses portalets like Cloverdale or MOJam
- big water jug and lots of bottled water
- firewood and firestarting material (most campgrounds are denuded of firewood) Make sure it's local cut firewood. Many places don't allow you to bring firewood in.
That's the basics. I can get all this in a Toyota Coralla with 2 of my kids. I just did it for MOJam
