Yeah I did mine a couple of years back. When I pulled my carpet I saw all the rigges and uneveness that you are talking about. I poured foam and sanded all that down nicwe and smooth. Then I exposied with some cloth all over it. I then uesed that cheap rolled on bed liner. As for the wires I ran them all under the trooper in wire loom and pop them through the floor where they need to come up at. I used them u clamps to secure the wires in the looms underneath the trooper.

With all that I did on my trooper I do have alot more noise and heat coming in my trooper. I would think that the line-X would help some and I am planning on going that route with mine. The thing is that the rolled on stuff that I got is thin and hard as a rock. The line-X stuff is thick and stays almost rubbery. The only down fall would be cleaning it. I had my bummber spraied with the line-X and they looked real nice but you could never get the dirt stains out of all them little pits. I talk to my friend that sprays line-X here in town and he said that he can spay it slick so I will proably get him to do that to mine so I can clean alot easier.

Later,
Daniel
