A thought to make a lighter stand, if doing it out of wood, find yourself a pallet, one of the lighter ones and cut it down to size for your platform. If it's a newer skid the wood should last several years and they are really sturdy, alot lighter than using 2x4's. Switch to regular wood, not pressure treated, is lighter and should last a good while if you don't leave it out year round.

Just some thoughts.
