Now that I have your attention, lol.
I thought the title might get a few laughs.
This is a reminder to those wiht bedmats or plywood in the box to lift them an clean the bed out at least once a year. It had been almost two years since I had done this and the amount of crap under the plywood was disgusting, (BTW, I have a sheet of 3/4 inch plywood cut to fit painted black and bolted to the floor of the bed). Twigs, leafs, bark and some rather pertrified sand in there, after sweeping scrubbing and a trip to the car wash the bed is clean and crap free.
So clean em up or might wind up with a tree growing up the bed. (Someone posted that happening to them last year, lol).
