You have to unbolt the driver and pass. seat pull back the carpet to expose the floor below, you only have to pull it back about 14 or 16 inches, but it is time consuming. maybe an extra 30 mins. per side, not too bad. The step actually has 4 bolts that hold it to the truck, 2 are in the floorboard, below the seat/under your feet, the other 2 are on the bottom of the rocker panel. Ive had one of my steps, completely dissasembled, I would say its a good design overall. If need be parts could be replaced pretty easily. I think from start to finish with wiring it took me 4 hours to do both. You need to make an effort to hide all the wires that come with it, I think there is 5 wires per side.
