4.88's (now) and 33's (285's), V6, 5 spd.

Pulled a utility trailer at 3000 plus a couple of times on flat land, I wasn't overwhelmed with the performance... Even with the old 4.10's it was not a Mack truck. Pulling 3000 plus on a regular basis up and down hills is going to be a chore for the 3rd Gen. I would suggest another choice in tow vehicles if this is going to be a semi-daily thing (towing that kind of weight.)

I tow a 1300 lb. Wells Cargo enclosed trailer (loaded) three to four times a week and it pushes the 3rd Gen. around quite a bit. Food for thought.
