bed liner
I would definately save for the Line x it is the way to go. As for the rails, I got mine under the rails with the intent to get a Cab but have since scraped that idea so I'm thinking of getting the rails sprayed. I would asked the Line X dealer what he though, the one I dealt with was a real good guy and I dont think that they would steer u wrong. It seems to me though that the rail caps u want to use might not fit with the line x under it. Mine is about 1/8 - 3/16inch think.
Oh and I know what u mean about the wife. Mine told me I stunk today after installing my FP guage. I told her it was my new colgne, #2 Diesel and then I gave her a big hug, she hasnt talk to me since about noon, LOL, may not be bad thing though.
Any way thats me 2 cents
