There is quite a mix of minimalists all the way to the other extreme in this thread. We tend to be on the lighter side, getting away with our kitchen box, small folding table, chairs, tent, 3.5" REI mattresses, an awning as well as our mountain bikes.
With a 3 month old added to the mix, wife and I have contemplated getting some kind of RV, but when it comes down to it, it's hard to beat the efficiency of throwing our camp boxes in the 4Runner and going wherever we want without the limitations of towing offroad and dealing with 55 mph towing speedlimits in California. I used to have a Toyota pickup with a Fourwheel Pop Up camper, but hated taking the unit on and off the truck and equally hated leaving it on the truck fulltime. Worse yet, it seems the moment we would get to camp and get everything leveled and in camping mode, we would want to drive somewhere. Never again will I own an RV that can't be disconnected from the main vehicle. We have looked at everything from tent trailers & A-liners to jumping jack/RTT style trailers and hardsided RPods...nothing really seems to check all of our boxes. So until that time, we seem to be doing okay with our basic setup.
