If you're handy give this a try:
We used 2x4's, some rope and eye hooks into the rafter studs in the garage, works awesome and economical, less than $10!! My husband put screws thru the hardtops bottom mounting holes with rubber washers while it's hanging just to secure it a little, (gets a little windy up here). We just put the top back on for a roadtrip otherwise it was hanging up there all summer. I have the 3 piece freedom top, just the back half goes up and I run with the front 2 on. https://www.jkowners.com/forum/pictur...pictureid=2021 https://www.jkowners.com/forum/pictur...pictureid=2022
you could add a pulley system to this and park right under it to do it alone. It took 2 guys to get it up there and back down.
Sorry, just logged back on. I need the cart that will store the doors and the top. Good looking wooden version, I considered making one of these but wanted something that wold take care of the top and doors in the same footprint.
