I am looking to buy an s10  for carrying tools, steel beams, a generator and maybe moving furniture,
would you recommend a 4 cyl or a 6 cyl...a 4 cyl might save me on gas but it might wear out quicker
from hauling weight as opposed to a 6 cyl that will take more gas but last me longer thus less mechanical
problems and more power.

2.2 L 120 hp (89 kW) I4
4.3 L 165 hp (123 kW) V6

Any comments are welcome....  thanx  

I'd go with the 4.3 myself . It won't use as much gas as you'd think it does , as long as ya keep it tuned up and oil changed . You'd kill the 4 cyl and prolly use more gas depending on the weight you carry . Not to mention you can pick up some mpg by gettin a standard tranny vs an automatic .
