Chip (Bud’s son) and I installed my set. The passenger side is pretty easy but the driver side is tough because of the KDSS stuff. Since there is no drilling or cutting, the only tough part is that you need at least one, better two friends to help you get the slider in place. The frame plates on Bud's are huge 3/8" thick with massive 5/8" bolts. Then with 6! legs and top mounted gussets, they aren't going anywhere. That's why I can confidently say they are the strongest slider on the market just from the sheer amount of metal used.
As far as holding up, my sliders are the prototype set, so all that rack bashing on the test set is the same slider. Then they took it again during Appalachian Toyota Roundup where I was wheeling the mud covered rocks crawls (east coast wheeling is like west coast rock bashing mixed with south east mud bogging' is that makes sense)
Now there are a lot of good sliders out there, they all do their job and protect your body so you really can't go wrong with any of them. I obviously sold my last sliders because of too much deflection and knowing how much I use the slider to wheel in rocks, and I really needed a kicker, but that's not to say that that last slider didn't absolutely save my rocker panel in California last summer, because it did.
I do like though that I wouldn't have to drill, and I like the leg arrangement for minimal deflection, especially when really slamming these sliders.
