Only thing i dont care much for with the powered units, they eat up bed space. Ther seems to be complaints about them failing as well. But you never hear of anyone complaining until it dont work...lol. Most the complaints i hear of around here is in the winter when they freeze up and cant open them. Old Skool = MANUAL OPEN works for me just fine. And if you wanna keep people from stealing anything out of the back of your truck, go get you a furnace transformer and clamp a wire to it to your box, ground the other end... they`ll only touch it just once. (hehehehe) It stopped the neighbor brats here really quickly... they walk on the other side of the road now.
