When I was in high school, I figured out a way to remove the top from my '72 blazer....solo. A variation may work for you.
Now, to start things off, I have no idea how much a wildernest weighs...or how it mounts to the truck...so take this for what it is worth.
I used a simple 8' long 2x4 as the only "tool". After the top was unbolted (12 bolts, IIRC), I would stand up in the back of the blazer (bent at the waist and knees), then using my legs I would lift the back of the top about 4 or 5" off the bed rails. I would slide the 2x4 under the top / over the bed rails so that it stuck out either side about 12 - 14 inches. Now it was a simple matter to pull the top strait off the back....no risk of it falling off to the side because of the 2x4 sticking out.....once almost all the way off, I would simply lower the back end to the ground, walk around and pick up the front end, so the wieght was primarily on the rear 2 corners. It was a simple matter to walk it back a couple of feet on those two corners, and set the front end down. It literally took about 10 minutes....7 of those were unbolting the top. It would go on just as easy.
If you don't like the idea of lowering it to the ground...build a pair of collapsable saw horses (brackets available at home depot, sears, etc) about 6' long and just a couple inches taller than the side rails of the truck bed. Set them up next to the truck, as close as you can get them while allowing you room to get the truck in/out. Again with 2x4's, lift one end of the wildernest with your legs, and slide the 2x4 under the wildernest, with the ends resting on the saw horses. Repeat for the other end. Then simply drive your truck out from under it. Reverse to install the wildernest.
good luck!
