You have the 3.23 or the 3.42 gear? Just curious. 

I have the 3.42.  My tires are also the same size as posted on my door so no loss from heavier, larger wheels.  Gear ratio, as you know, is a significant variable.  The same truck as mine except with the 5.3 V8 and 3.08 gear ratio is rated to pull 900 lbs less than my 6cyl truck!

Learned early on that gearing is one of the most effective modifications a guy can make. Not as flashy as some others but really effective. :thumbs: Your truck is going to be fine.
