Folks with no windows or even a top certainly dont have carpet. The vinyl seats do ok and most of the rest of the truck is either metal or plastic anyway. These people who leave their Jeep exposed to the weather can and will experience problems down the road especially with electronics. A lot of people put marine grade audio systems in but the rest dash its just a matter of time. Those folks either dont care or have plenty of money. I would protect my investment. Its up to you I guess.
