You read my mind! I'd love to see pics of what that looks like.I realize this is an old thread but thought I'd post some related information.
I recently purchased a used Bedslide via Craigslist. I bought it from a guy who was using it in his short-bed pickup. I'm going to install it in my 2005 Suburban.
The mounting configuration for the pickup was very simple. All we had to do to remove it from the bed of the truck was lift the rear of the Bedslide and then pull it back to remove it from the anchors at the front of the bed. No tools required! I was amazed and pleased that it removed from his vehicle so easily. With this configuration the bedslide can be installed and removed from the truck in just minutes. Gravity holds it in place. In this case, gravity held the unit in place and it was easily removed by two guys. Probably only weighs 100 - 150 pounds at most.
The Bedslide physically fits into the back of my Suburban with the 3rd row seat removed. However, I'm going to need to "engineer" some mounting points so I don't have to drill any holes in the floor. Unlike a pickup bed I can't just use the load and go gravity method with the pre-engineered engagement pins. I think I'll be able to use the mounting cleats for the 3rd row seat - the cleats are beefy and will support quite a cantilever load. I'm considering using some J-hooks to engage the cleats then fasten the J-hooks to the a flange on the Bedslide.
Clear as mud, right? I'll consider taking some pictures if I have time.
