I had the entire floor of my 91. 5 Dodge diesel rhino lined. Drove it to the shop with the seat and belts loosley in place and removed them prior to the spray. Took out the seats and cut a 3/4 inch pvc conduit in half and heat formed it and siliconed it to the transmission tunnel to create a chase to feed speaker & amplifier wires through. The Rhino lining was fantastic. There was added road noise beyond the factory carpet and pad, but it was not unbearable. The only bummer with this floor material was when it was winter and snow from my feet would melt on to the floor and re-freeze on the floor over night. Talk about a slippery floor! Make sure to leave a rubber floor plug accessible prior to the lining application so you can hose out the floor when necessary. Leave the bolts in for the seat and belts andtape over the heads and threads for re-install. The transition at the door /floor area can be difficult to create a sanitary looking installation. I put a plate of aluminum at the door jamb tansition. If my current 2005 truck were not the primary family driver I woulod do the same rhino spray to it. Good luck.
