the wife has a wrangler, but we dont travel with it, instead we use my tundra with a cap on it because it allows a lot more room and it is a much more comfortable and quieter ride. if we did have to take her jeep, then i would use a trailer...either a camp trailer, or small utility trailer with RTT. i dont like an RTT on a vehicle for many reasons, the main reasons are we sometimes pull over at rest areas to sleep and deploying a RTT isnt doable. also, i really dont like having a vehicle trapped by the RTT in case we had to leave quickly and the tent was deployed.
we went with a small toy hauler camper to go with the truck and camper shell set up. its a 5x8 hard side with A/C, slide out galley and various storage. the entire back end is a drop down door and intended to drive a 4 wheeler up in it and carry on trips. i like that because it makes the camper more versatile where we can load a lot of stuff in it easily (big totes) or just drop the back door and have a nice scenic view, etc. im sure a utility trailer with RTT would also easily accommodate a 4-wheeler, kayaks, etc.
a camper like that makes a great base camp where we can store everything in the camper and have the vehicle freed up for driving and exploring. i can also load a lot of crap on the camper, like a kayak, extra fuel, solar/battery set up, etc without having to mount stuff to the vehicle.
i also like the camper because we can park it and keep it ready to go at a moments notice. if we took the jeep, we would have to load it and go thru all of that as well as have to have a seperate place to store all the gear, where with the camper, all the gear stays in it.
another benefit is having the camper at home where sometimes when several of the kids visit and the spare bedroom is full, they can sleep out there and its handy during storms because when power is out, we can use the solar in the camper to charge phones, flashlights, etc and cook with the slide out galley.
