We do the Jeep thing as a family. We have a pretty good sized jeep with lots of stuff done to it. Here is a video of myself, the wife and the two kids in the back of the jeep. We have built the jeep to be good offroad and also safe for the kids with the addition of a roll cage inside the roll bars that came on the jeep. We also have netting to help keep the kids hands inside, stuff from hitting them if we do roll over and we tie down all our gear. I guess the roll-over trainers did teach me a thing or two afterall.
Here is the vid. It is about 3 minutes long and there are two videos in it.
