I ordered the ARE topper (best one they make) in early October. The frameless window would not close on the tailgate and workmanship was not right - holes drilled wrong that looked like crap, etc. Returned it and the second one came with the rear window assembly fitted into the cap crooked. Two months went by, got sick of it and got a refund. ARE was supposed to be one of the best. May Leer? Maybe a tonneau cover would be better - harder for them to mess up. I'm driving with an open bed for now.
DO NOT BUY FOLD-A-COVER FROM STEFFENS AUTOMOTIVE! You will never be able to remove it and reinstall it because of an obvious flaw that they know about, but refuse to correct. All the mounting hardware is custom machined aluminum, and all the fasteners are stainless, creating a dissimilar metal reaction that oxidizes the fasteners into the hardware causing the 1/4" Stainless bolts to break off if you try to remove them. Not only that, but they sell replacement hardware kits with about $20 worth of materials for $100 plus $12 shipping! So a couple years after paying over $800 for a Fold-a cover, if you need to remove or adjust your cover in any way, you will be forced to pay $112 for a new hardware kit made out of the same faulty materials.4 bolts and the entire Fold-A-Cover is off the truck. basically there are a set of rails that attach to the top of the bed through the stake pockets that are semi- permanently attached. Then two clips are mounted and form part of the hinge system for the front 1/4 of the cover. If you look down from the top the cover is divided into quarters, with the back 3 panels able to fold up on it self creating one area up near the truck cab that is still covered. Locks on both the front and rear panels allow you to lock it up fairly securely. Like I said, I am on my second one and they work perfect for my application. I can even leave the 5th hitch in the truck when not towing and close the cover.
