Years ago, I had a 91 ranger I bought a rubber, non slip mat for. It
appeared to be made of recycled tires and had to be cut down to size for a
good fit. I bought a new ranger (sold the other one with mat a few years
ago). I'm looking for one of these and can't find them anymore. Every one
want to sell a liner or a $400 spray on job! I just need a basic $20 mat.
Thanks, bg

Bought a seriusly rugged bed mat from my local dealer 2 days after I
bought my SD.  $60 and it's taken a beating over the years.  It sits
on top of my Line-X liner to keep stuff from slipping around and I've
hauled broken concrete to scrap steel in the bed.  Nary a cut or
tear...  Not sure who makes it tho.  I'll try to remember to look at
it tomorrow when I get to work.

See if you can find anyone who works with large conveyor belts,  any big
pieces that they throw away make an indestructible mat for a truck bed, and
most of them are rubberized and or even rough finish so things don't slide
around. Best of all it's free, the belts get torn and worn and then thrown
out, but the material is still perfect for making truck bed mats.

Found mine at Pep Boys but I'm sure JC Whitney, etc., would have them. Good
Luck!
