Been giving this a little more thought and here's what I come up with.
#1: It would only deployable from key bases like a CV Group (Say the Large Uncapurable Airfileds). It could either be towed by a Tug Aircraft or equipped with the 6× Gnome-Rhône's (950 hp each) and RATO's (which were required for both Powered and Towed takeoffs under full load).
#2: Once landed it would essentially become a mobile Vehicle base.
#3: It would have limited vehicles available. I.E. M8's, M3's, M16's etc etc
#4: It would carry no Vehicle or Airfield Supplies and no Troops. These would have to be flow in via C47 as it is now. Reason being someone could just land this monster on the edge of their damaged field or town and run a M3 out the door and drop field supplies, bail and repeat and have a field/town resupplied in less than 5 minutes. Same thing with troops at enemy Bases or Towns.
