I would break down a bulldozer and a bus and combine them together. Then i would put an extra gas tank in the back. Armor would be easy to weld to a metal bus lol. Ive always had this idea, i even drew it, of a gear mechanism that when the vichle was moving would run a giant chain saw like chain around the bus, cutting anythin it touches, it would move slow but be powefel enough to take any zed. But i have a vivid mind.
Needs a cage.
