Oh, Lord.:trout2:
That inline 5 is a weak sauce engine, only the 3.7L I5 would be much of a threat with 240 hp/ft-lbs.
Depending on how your truck is equipped and his is, I don't think he is going to be much of a threat anyways.
First, engine/trans: 4.7L V8/5speed auto vs. 3.5L I5/4spd. auto, 235hp/300ft-lbs vs 215hp/230ft-lbs. Winner: Dakota, even with the weight disadvantage.
Second, towing: the Colorado was not designed to pull more than 4600lbs., the Dakota was designed to pull up to 6600lbs. Bar none, the Colorado was a poor replacement for the S10, which could pull more than the Colorado(but not the Dakota still).
Third, size: the Dakota is hands down bigger in all dimensions, including interior space, which is the most important aspect with midsize trucks, and the Colorado is still designed like a compact while being called a midsize.
Finally, I think your friend is giving you hard time because, int he back of his head, he knows he fucked up and bought a shitty truck.:jester: Tell him what I posted and you may be able to save your friendship, otherwise, your just going to hurt his feelings and make him look like a dumbass.:explode:
