Composite decking is very slippery stuff.
Once I had it bundled on pickup with 5000lb strap and still few pieces managed to slide out.

I will slip on itself - not so much on a bed-pad. Altho any wood will slip a little if you bounce your truck around no matter what you use, so just make sure your anchors are installed and hooked correctly and you'll be all set. I have comp decking on my camper, and it never moves ...
