youre going to need something to slide on, pvc is good, and if you have the tools, steel is best. but sliding on wood wont be too fun, especially in summer when the wood will be soft
Just throw something together that looks like it will work, then just add a butt load of supports to stabilize it. I through a 10 ft rail together in 20 min and it's solid as a rock and works perfectly.
