Well, I'll throw some sugar on the cereal! How about a Recon. Lightweight, comes apart into 3 sections so very, very easy to remove and store. Sturdy, never had a hint of problems with it. Of course, it's NOT got air bags, slides or all the stuff that jacks up the price, but it's sold, stable, and strong. Best of all, it's horribly simple!
I needed something I could easily remove from the truck bed myself, without help. This one fit the bill perfect.
