Hi everyone...I haven't been on this site for some time but hope to be back on a regular basis now. I just recently purchases a 2001 GMC 2500HD with the 8.1L/Allison transmission. Does anyone one else out there have experience towing with this setup? If so, I would like to hear from you. What type of gas mileage, weight of Trailer, and at what speed do you average when towing? I'm not interested in turning this into a diesel vs. gas debate, just interested in others experience with this motor if you have one. My current TT weighs in right at 6300-6500lbs so I am well within my limits with this setup but I am curious what real life results people are getting. Thanks in advance for your feedback....Sundevil
