For legs, I went with Home Depot saw horses and a twin beam construction. Wood beams can be purchased at any length or home made. I made my own 8" Eye beams which are 44' long. Leveling is done with wood shims under the beams where they sit on the saw horses. The saw horses have built in 2 x 4 pockets for shelving. Pictured is my staging yard, still under construction, which will have 12- 22' long spurs.
Beam construction allows for dual use which is above and below. Great if you want an under ground subway.
Running wire is a breeze. I just lay it down between the beams.
Finished platform height is 46". Subway height is 34".
