I'm not a fan of store bought drawers slides either. Instead JBoot51 on here showed me the light, and I used roller bearings on 12M bolts inside unistrut on my under-tray drawer. A little bit more effort measuring, drilling, etc but they look very sturdy. Only had them on a couple of weeks, and only bitumen so far. They'll get their first test in the high country after Cooma.
