Installed heat blanket under rug to keep out heat from engine and exhaust. Since this a no A/C truck, the blanket makes a definate difference in the amount of heat radiated into the cab durring the summer. It is the same stuff used ion the floor of racing cars. In the winter it also keeps the cold from radiating in thru the floor. Brutal stuff though, youdefinately need to protect your arms when cutting it, I didn't and my arms itched for a week.
