I have the AMP BedStep, too. It really helps getting into the bed of the truck especially since I added the leaf springs to beef up the rear suspension which made it even higher off the ground. Very good quality and a permanent installation. The only negative is that you need the clean the snow and ice from it regularly in the winter to make sure it doesn't get frozen in the up position.
