Nylon Sliders or slider rails, skids???

Hi Explorers

Has anyone had any expeirence with the Nylon sliders used under storage drawers in trailers etc?
I want to make a kitchen unit that slides out the back of the ute. I guess I'm looking at the same concept as the Drifter type unit, but maybe not removeable from the ute. Previously I used guide rails/tracks and wheels from a panel lift garage door but it adds some weight and a 40mm gap under the drawer that becomes almost unusable, (extra poles and not much else).
Anyone know where to get such a product?
