Theres a Comanche pickup down the street from me for sale... 4x4, manual trans, probably the inline 6 cylinder engine. I think it'd be a neat little beater to run around town in, maybe save a little gas. Thing is, it's got almost 187k miles on it, and some body rot, mostly around the rear wheel wells. Being unibody, I was thinking the rot could weaken the structure... am I offbase? It's got a 6' plow, asking price of $1500. Worth the investment? Any advice?
