If they had had that same mat in 4' x 6', I would have gotten it. Trimming the end off that one would be a bear! They also had 3' x 4' x 1/2' mats for $26. But, if this one tears up easily, I may get one of those. I didn't go for that because it was actually too thick (at least, for what I want). They had a 4' x 6' x 3/4' rubber mat for a horse stall (I guess). This one, being recycled rubber, may rip just as easily. But, the one at the front of the rack had a chunk ripped out of one side and I 'felt' it. I also went to Lowe's and they had one similar mat, with a 'chevron pattern'. LOL I just wanted something that would cushion my knees a little bit, give better slide resistance than the Line-X spray-in liner I have, give a little bit of extra protection against dents in case I drop a scuba tank in the bed, and have some texture so that dirt and water that gets on it can fall down into the channels and not be held right up against whatever is in the back of my truck. A RAM logo in the center would be cool, but I guess you don't always get what you want. I put it in the bed upside down, marked it at the end by the tailgate, put a fresh blade in my utility knife and cut off roughly 5' from the end, flipped it over/around, and voila! I suppose it's not everyone's cup of tea, but it is just about perfect for what I wanted. However, I will be putting a bed cover on, so that should never be an issue.

I'm not too worried about it flying out of my truck if I'm driving with it in the back, nothing on it, and no cover on the bed. The specs say it's 3/8' thick, which seems correct. A 4' x 6' recycled rubber commercial door mat.
