I'll only buy chevy's or gmc's so im woundering if i should buya 1500 or 2500. I know i want a 4x4 reg or ext cab. Plus i'm going to be plowing. This time next year i hope to be pulling a walkbehind w/sulky or encore z34 with backpack,trimmer etc. Single axle prob. 6x12. Undecided as to open or enclosed and what brand. What do You think?
