Truck bed carpet kits were very popular in the 1970s and early 1980s and there were a lot of manufacturers making them. They fell out of vogue, as they say, and yet there were still a few who continued to make them.
Recently there has been a resurgence of interest and demand for the carpet kit because it is still quite useful depending on how you use the bed of your truck. They are made of automotive style carpet with plywood frames and padding and are meant to be used inside the bed that has a camper shell or truck cap so that the carpet stays dry. It can be made into a bed or sleeping quarters when needed as well.
Vaca Valley Truck & SUV has sold a number of these in the last couple of years and we can ship them all over the country. They are relatively inexpensive, even after shipping by common carrier. Give Kevin at call at 707-447-9905 with any questions.
