there's no way I'd even try it without a diorama to show it "doing its thing"... A kit that big HAS to be shown that way, IMHO..
That said, and this might shock some of my "regular readers", but I think I'd actually spring for that kit, even though the price is WAY too high, IMHO... But I'll wait until the price goes down a bit more if this kit's a new release...
But if I were to do this, yeah.. Definately a diorama, most likely of a crew recovering an IED-damaged M1 or RPG-damged M109 or the like...
