Took my little niece's out for a 4x4 after all the rain and this mud hole got me by surprised. It was on a track that had been graded but obviously with all the rain the fun ruts where still there just hidden by 2-3 foot of crusted over mud.
Anyway got all the carpet out before the trip. Originally I just had the driver seat in to get to work and back, but the kids really wanted to go out so all the seats went back in.
First thing I noticed with no carpets/seats was the noise. It doesnt bother me, but but engine noise and road noise is a little louder. The thing that did bother me was the heat, the car was defiantly hotter with just the driver seat in. Its alot better with the seats & rubber bucket matts in and hasn't been as bad driving to work and back.
The rear passenger floor pan being right above the exhaust gets so hot you could cook on it lol. I was worried the rubber mat would melt but it acts like a insulator and the mats just warm to touch.
I donno if bedliners have any insulating qualities but I was looking at a product call thermal shield to spray down before the bedliner. Its a ceramic insulating paint they use on housing roofs.
