truck bed mat

I put a bed liner system in my truck that incorporates form-fitted, plastic side pieces to protect the bed with a rubber mat to protect the bed's floor. It's THE best bedliner I've used, head and shoulders over the one-piece bathtub liners and Linex/Rhino spray liner. I use my truck for work, too, hauling equipment/tools and all kinds of job site debris. It's holding up great. The mat is plenty durable and my camper stays put.
Outstanding customer service, as well. There was damage during shipping, but it was remedied past the point of my satisifaction within 3 hours of my first email contact. No balony. Good people.

Geeze, I must not be doing it right. I use 1/4 inch thick yoga mats and have never had a problem with the camper shifting. Really light weight and cheap. This will be our fourth year using them and aside from a little staining and dirt they are holding up quite well.

I picked up one of those horse mats from Tractor Supply and promptly put it back down. Dang that thing was heavy.

It seems to be difficult to discover if a bed mat is molded to fit the depressions and ribs in the floor of the truck bed, or is the same thickness overall...

Anyone own a brand that is molded to fit the floor profile?

Im using the 1/2 thick rubber mat cut exactly to fit the box and comes in two pieces. It's cut out for the wheel wells and is a nice snug fit. Camper does not move a bit. They are made to fit each truck model.

On our 2006 Ford F-350 CC, XLT 8 ft bed we have a Line X spray in bed liner, several Home Depot mats zipped tied together, the camper still shifted due to road conditions. So I am looking at getting a Summit Racing Dee Zee mat, putting the Home Depot on top of that, making a cradle for the front of the camper, between camper & front of p/u bed. Also going with the Lance Cabover Struts. Our TC does a lot of porposing. The TC is a 2003 Lance 1161.

Tractor supply sells a 4'X6'X3/4" rubber matt for horse stalls. Its great for truck beds. $29.99

Tractor Supply, I think the one I got was at least a half inch thick, maybe more.

We are using horse stall mat. Second cheapest rubber protection you can buy

X2 on the TSC mat,1/2" thick and cheap....

Like CB9 I have a spray in bed liner and have never seen any noticeable movement of my old six pack or the new AD 86fb. but it is rough and the 86 does have rubber around the outside, so the question is, do any of you with the spray liners use a mat just to protect the underside of the TC...
