if this is a driver, nothing will hold up more than 2-3 yrs
i looked at trucks at shows and asked the same question to everyone i saw
i used trex plastic decking from hd, it's solid composite 5.2''x1''
hd stocks grey, but they can get 4 colors
this is the unpainted bed for test fitting
all cuts were done on a table saw. since it is a full inch thick i was able to recess the (soon to be painted) strips bellow the 'wood'
biggest problem i can say, is it slippery as heck.
nothing stays in place
