Hey folks, I have been looking thru the diffrent ways to insulate the cab of my truck, mainly the floor and all I can see is if you are going to use carpet. Well I'm gonna use my rubber floor mat and I didn't know what to do about the bubble/foil insulation I plan to use or sould I do something else. This original mat just lays on top of what ever is on the floor. Has any one ever just used the rubber mat? If so what did you do about heat and road noise? Thanx in advance! Mike :confused:
