I want one of the Humvee's personally. But if I was to get the tractor trailer truck. I'd build a custom trailer to go on behind it. Pull a super sweet HQ... just image all the SAWS and M60's... couple custom M2 .50 Brownings
... a Vulcan... heh heh heh. But I don't have that much money to even START a project like that. Back to the more affordable Humvee's
