Sliders were something I knew I would add to the mix when building the Tundra. Fortunately for me, I don't really have ot factor in a loss of power from additional weight with the monster 5.7 in the truck. Fuel mileage from added weight, well it's a consideration but not a limiting factor.
I wanted good quality functional sliders that acted as both protection from off-roading, provided a place to jack up the truck from,offered a step for my Wife to get in and out, and were not tubular so that I knew I wouldn't have any possible issues with our dogs getting hung up between the tubes. I ended up purchasing the Slee Sliders and they are an amazingly fabricated piece of kit.
