Or rather, jeeps.
I have two jeeps going at each other in an on-the-go brawl, each driver trying to take the other completely out of commission. The first is a pretty damn big, burly, patchworked, survive-a-couple-apocalypses all-terrain deal (this is a post-apocalyptic scenario). The second jeep is a typical sized, shrimpy compared to the other one, with all its original parts (which probably means not very good parts, either). The good guy is in the big one, trying to get his pursuer off his back and put him out of commission. It's pretty much out in the middle of nowhere, mostly sand/dirt terrain, so there's no pavement, no walls or guardrails.
My question is, what sort of things could a larger vehicle do to an opponent to either roll him, crush him, or just plain blow the hell out of him? And what could the smaller vehicle do to defend itself or even take the offensive? I don't think the larger vehicle is so large that he can just roll right over him like some monster truck, it's just a burlier, sturdier vehicle than its rival. I wasn't sure if it was so easy to muscle a vehicle into the ground or not. If it is, just say so.
If nothing else, I can just have the driver whip out a gun. But I figured that would be too easy.
If it helps, both vehicles are topless. Thanks in advance.
