I have a 3/8" thick rubber mat that covers the entire bed of my DC-
very heavy/tough etc. I went to a commercial rubber supply place &
bought a 6' piece of rubber for a continuous potato processing
conveyor belt.  It comes in different widths, I believe mine was 5'
wide, & I just cut it too fit correctly around my hoops & cover the
bed.  I throw engines, rocks, all kinds of nasty stuff on it, & it is
bomb proof.  Cost about $130, 6-8 years ago.  I can pull it out by
myself to clean the bed, but usually just hose it off in place.

YMMV,

Mr. BZ
