So I'm tired of the carpet in my truck. There are stains, it can hold in moisture and smell, something else to clean, etc.. I'm looking at rolling on a bed liner inside. I've been looking around at reviews and it seems Monstaliner has some of the best reviews. I'm also looking at Al's liner, Durabac, and Raptor. I know something like Linex is more durable and I'd go with that if I were coating the bed, but this is for inside the truck. I doubt my boots, dog's paws, sliding a cooler or Pelican case, etc. will cause enough damage. Before I lay down the bed liner, I was looking at adding some sound and heat insulation first. Some options I'm looking at are Al's HNR and Lizardskin. Al's is much cheaper and both products in one. Does anyone have experience with these?
