I had LineX install my PullRite superglide with underbed mount. I bought my truck used and it already had rails that were rusted out. I am not very mechanical so ANYONE else would have done a better job than me. They even ground out my old rails for free since I was giving them so much business. It also saved me from having to take it somewhere to get the old rails off, over to LineX to get it sprayed, and back to somewhere else to get the hitch installed. They even put in a tonneau for me. One stop shop, everything has been perfect. I figure a shop that does truck accessories knows enough.
