Thanks for the input. I have a Ford Expedition that tows great. I figured the Z71 with the longer wheel base should do even better.

they tow good but lack some power. i had a z71 but upgraded to a crew cab with the 8.1

check out www.ls1tech.com and go to the truck performance section...lotsa info for you there.
