I agree. It's not something you want to go cheap on if you plan on REALLY using them.
But then if I was going for the $600 HD ones because I felt I NEEDED that kind of protection then I'd be looking at a 4-point harness, roll cage, bead lock tires, winch, bumpers front and rear, front locker,.... and be building a rock crawler.
I personally only want something that'll protect against the occasional tree, a rock here or there, and break-overs that are mostly dirt. I have no intention of rock crawling, nor do I have the type of terrain for that around me. Honetly they will be used as steps and guards against shopping carts and car doors 90% of the time.
Considering my thin walled tube steps (only bolt on at the ends, btw) held up to the truck sitting on them and rocking back n forth on a break over I'd say just about any slider would be fine for what I need. Hell, the step bars would not have bent up and put small dents in the rocker panels if they had a brace in the middle. So some thicker steel bars with reinforcements and 3-4 stand offs welded to the frame should be more than enough for my needs, and probably the majority of people on here... I can't see many people rock crawling a new, nearly $30k truck without heavily modifing it anyway. Those people would probably be building their own roll cage and boxing the bed anyway! :lol:
