I would like to get some opinions on runners/slides for extra long drawers. I am planning on building a raised floor in the bed of my 6&1/2 ft. pickup bed with about three drawers. I'm sure some of you have a similar setup for your truck or have seen some. I was thinking of making it in two sections, the forward section accessible by lifting the cover but the rear section with drawers, so the drawers would be about three feet deep. I found some 3' slides in Rockler but they want $150 for them! I considered a dove-tail runner in the center or maybe installing wheels/caster on the bottom of the drawers at the corners and have them sunken or recessed so just a little of the wheel protrudes from the bottom. Anybody got any ideas?
