Jim,
Our family is facing the same situation. Our 11 year old twins moved from Cub Scouts to Boy Scouts. We now have 3 boys that are into camping and when my wife and I want to go with we have a very hard time getting all the camping gear and the five of us into her Honda Odyssey let alone a Jeep.
I have been thinking that maybe we should get a small cargo trailer. We could leave most of our camping gear in there all the time. That would free up the interior of the vehicle for people comfort instead of having gear crammed around people's feet like we do now.
I am thinking of getting a 2007 4-door Jeep Wrangler but it would not have enough cargo capacity for the five of us to go camping. I would have to get something like a Chevy Suburban to carry all our stuff. I don't want to drive one of those to work everyday!
