Tommy, have you considered building some nerf bars for your Gator? They would be the same basic shape as the bed rails, just larger diameter and with mounts that would go under your floor area. A lot of guys that do some serious trail riding on their UTV's recommend them as the next thing to add after a front brush guard. I have the brush guard on mine, but I have not bit the $175 bullet for the nerf bars yet.
There is a site called Hunterworks.com that designs and builds add ons for Rhinis, Gators, and RTVs, but refuses to build anything for the Ranger. Polaris has a pretty good selection though.
