I have the go rhino RB20 boards and hate them. The problem with them is the mounting brackets are basically J's that hang a couple inches lower than the boards and create what effectively are little sideways plow's 4 on each side of the truck. They scrape on everything. I've done a couple of overland expo's and their ride with instructors for their obstacle course were like "wtf" and those courses aren't designed to be bad, tons of sprinters do those and probably made less contact with the ground than me. The dominator D6's look like they have a better system. I'm looking for some sliders (weld on or frame squished or whatever) but seems the reviews are very mixed on those, just a word of advice especially for the less experienced, think about what's going to make contact with the ground or rocks or whatever when you're picking a solution like these. I consider myself pretty tame off road, I'm not out there rock crawling. Attached is a pic that isn't great but you can see how bent up the brackets are getting and thats one of the better ones.
