I know the RSE steps aren't hardcore sliders when compared to some other options, but they are solid. Install isn't hard either. As long as you don't hit the body bolts with an impact, I think you'll be just fine. I used an 18" breaker bar, and did 1/4-1/2 turn, before reversing 1/8-1/4 turn. This really helped things to go smoothly.
When we climb into the Jeep, we don't step onto them square, but at an angle. So, they're certainly not wide enough for a full foot length, but they feel like a normal step to me. They'd also be adequate to stand on if you had roof-mounted accessories. I'm 5'10" and my wife is 5'2". The RSE steps will definitely keep us from sliding in/out of the seats and damaging the outside seat bolsters.
Some measurements for reference:
The step portion is ~2.75" wide, and ~49" long.
My Jeep is a 2023 392XR, with 37" Nitro Ridge Grappliers (approximately 36.77" according to Nitto).
The top of the step is 14.75" when it drops down. For us, this will go up just a little when I get around to installing the Clayton 2.5" Overland lift.
Also, RSE updated their wiring harness for these steps. There is now a master kill switch that mounts under the hood right next to the battery. This will kill all power to the steps. In addition, there is the 'sleep' switch which mounts by the OBD-II port and that is used to disable the steps while off-roading, washing, etc. If you're Jeep isn't going to be driven for several days/weeks, it's recommended to turn the steps off at the master kill switch to eliminate any parasitic power draws.
