Ken, To be quite straight to the point: The cost of cuting the 5/8"thick steel
x 2' tube filled with concrete, Boring the hole ( 24" tube will not EASILY
slide into a 24" hole) and will need a large amount of concrete to stabilize it
anyway. add a small crane to set it ( it has to be perfectly Plumb to go in the
hole and is verrrry heavy) Even when doing this all yourself, Just the cost of
equipment rental will be far more than doing the base as the manufacture
suggests.
Be safe the Manufacturer did engineering on the tower base for a reason.
