This thing for $44 was not worth a penny.

Maybe with just the right late model truck for a thin tailgate and nothing but some dry leaves it might be useful to somebody.

However, it catastrophically failed at 1/3 of its stated load capacity.

Now I am aware the instruction say remove the mats and have a 'slippery bed'. What does that mean? Scratched up paint and such?

My reply would be to find a better made bed cargo liner. Something with worm gears and a 1/8 thick pipe wall in 1" diameter.

But as it was don't even bother to waste your money if it is farm life for you. Just don't.
