I've had my RTT on 2 jeeps. On both jeeps, I mounted the tent to the crossbars, then removed the tent & crossbars combo from the jeep anytime I needed to pull the tent. That gets rid of most of the difficulty of removal/reinstallation.
On my XJ I picked up some used Thule bars off craigslist, on the JK I have the rhino rack backbone HD bars. They mount even easier than the thule gutter mount bars did.

My wife AND garage are both too short so I put together an el-cheapo crane with 2 8-ft ladders, a harbor freight winch mounted in the garage, a long 4x4 and some mcmaster pulleys. It's still a little complicated but it works pretty well.
I pull the tent off if I know I'm not going to be camping for at least a month and for most of the winter. I figured out 2 harbor freight dollys screwed together to form one large dolly hold the tent perfectly standing up on it's long side. That way it stores in a reasonably small footprint in the garage and it's mobile.
