The Floor liners are the way to go for protection. I had them in my Denali for 5 years with Rubber mats on top. I don't have a spot of dirt on any of the carpet. I sold my Denali and the buyer could not believe the pristine condition of the carpets and the trunk area. I visit many industrial sites, Steel mills, landfills, mining sites. smelters and trail around a lot of mud and crud. I carry lots of industrial minerals, samples and have made lots of runs to Home Depo. The liners have saved carpets from a lot of potential accidents.
