I have the AMP power step. As others have said, they are very expensive. Regular steps would be too high for certain older relatives to climb in my truck, so I was able to justify it. For the money you’re getting high quality components (IMO). The basic installation of the steps is easy. I had a relatively hard time with some of the wiring, which has to be routed through the firewall. Helps to have long arms.
For those that commented on steps providing protection for the side of the truck, AMP does sell an override switch that will keep the steps in any position you want, so you could keep the extended if you want to. I’ve had them for about 3 months and am very pleased so far.
