I think they said they weren't continuing their sliders any more...I might have that wrong.
That led me to look elsewhere and I really like how these use the 3 sets of cab bolts. They claim they'll hold up the truck.. maybe a slow, static lift using forklift forks in 2 locations on the slider. A drop down hit as often happens... I am not so sure. Of course they'll be waaaaaaay more robust than the OEM steps, but at a 100 lb weight penalty you'd want them to work as intended on game day.

I'm in a personal slider hell. I don't need them often, but in the tighter trails here in BC, road washouts etc. they would come in really handy once in a while. A local metal fab guy does great work and will do weld ons. Stout, and I know they'll work. Heavy, but frame welding.
The rocky roads look great. Weight penalty and still a chance of stoving in the cab.
There are light sliders that will handle incidental grinding and impacts better than oem steps, but won't handle the weight of the truck from what I can tell. Various configurations of bolting to the frame and/or cab and the risk is they either require drilling into the frame or a sandwich of it and both could be a point of failure, rust, buckling etc.
