I got home late last night from the Bantam Jeep Fest and my first task this morning was to turn the Jeep back into a daily driver, so I removed the roof top tent, the roof rack basket and the Trail Kitchen. All of that took less than an hour. I've got it worked out so I can do it very easily by myself, without any heavy lifting. What I do might help others so here are some photos. (These weren't taken this morning, they were taken at various points in the past but they illustrate exactly what I did this morning.
First thing was to remove the RTT. I do that with two 10' 2x8's set up as a ramp. Once I unbolt the RTT from the rack (4 bolts), I let gravity to the hard work, I push it over onto the boards and slide it down.
I install the RTT the same way, I just push it up the ramp and over onto the roof rack. No heavy lifting.
Then the rack basket comes off, it's roughly 4x6 and awkward and heavy for one person, so to remove it I drive into the garage. I've got crossbars hanging from the garage door rails that I hang the rack basket on, all I've got to do is unbolt the rack basket from the rack rails on the roof, lift each corner a few inches and secure it to the crossbars with a u-bolt. Once secured, it's a few inches above the Jeep and I can drive out and in under it. BTW I use this same basket on both Jeeps so to install it I just drive the Jeep I want to use it on under the rack, undo the u-bolts and let it down onto the rack rails on the roof. (In this photo the rack is held to the crossbars with chains but since the photo was taken I switched to u-bolts, which are much quicker and easier than the chains).
And finally, the kitchen comes out. First I remove the fridge, I carry that into the kitchen in the house to unload its contents and wash it out. Then the Trail Kitchen comes out of the Jeep. It's pretty heavy because it's sturdy enough to take the abuse of the trail, so I'd rather not lift it if I don't have to. The drawer unit attaches to the main kitchen with 4 bolts and then lifts out (the drawers are light and easy to lift). Then I remove the 3 bolts that secure the main kitchen to the Jeep and slide it out onto a Harbor Freight tool cart. No lifting, and they I can roll the kitchen to a corner of the garage for storage. Removal of the fridge, drawer unit and main kitchen takes all of 10 minutes.
Total time for all of the above is less than an hour, installation takes about the same amount of time.
One more thing, to store the RTT I've installed shelf brackets on the garage wall about a foot above the floor. The RTT goes up on those brackets agains the wall so it's off the floor and it doesn't take up much space. Also visible in this photo are the crossbars and the u-bolts that I hang the rack to.
All of the above is very efficient and makes it easy to singlehandedly install and remove these heavy and awkward items very quickly. I hope this helps someone else.
