After getting burned on a truck cover I've decided to be more cautious and get input before shelling out money for carpet. Any recommendations for, or against, any carpeting or opinions on carpeting will be greatly appreciated. Also, would you recommend standard, deluxe, sound proofing, mat backing, etc. There are so many options and companies and some companies are all selling the same manufacturer's product. So what does the hive say? BTW, going into an '88 K5. Won't be buying right away so I'm trying to take the time to do my homework first. Thanks for any input.
