Yeah, I understand what you mean - I hate it when I don't have the pieces to make an MOC have the look I want for it. Not much of a problem with LDraw, though! Have you considered just getting rid of the wheels altogether and making it a military hovercraft instead? If you do that, it can [theoretically] go over water too! http://en.wikipedia.org/wiki/Air-cushioned_landing_craft

I really like the upper part of it: good part usage, and it looks rugged. It's just the wheels that kinda bug me - they just look too small to reliably support the upper structure.
gee thanks for the comment oh and about the wheels that was the only thing i hate asell cos i cant find any more wheels
Really cool job! I love all the weapons and missiles and the huge wheels. The troop holder underneath is really awesome. And I love all the little compartments for soldiers and stuff. I think that the vehicle would be a bit top heavy though. P.S. check out my Millennium Falcon!
