Yep. 3.42. I just double checked my owners manual and max tow rating is 7,400lbs with the 3.42 rear end. We actually do have a few hills around here and the 3.42 isn't that bad. You can't run with the cruise on though, or it tries to shift you down into 2nd gear in a heart beat.
Yea, 3.42 gears are not the most desirable for towing. GM loves them for the MPG claims. My cousin had a 2005 GM truck with a 5.3 and the 3.42 gears and towing a 5,000# boat to Georgia a few years ago my F-150 with a 5.4 and 3.73 gears would flat run away from it while merging on the highway and passing semis even though the boat I was towing was 7,000#. It did fine once up and running but the hills in Kentucky and Tennessee through the Smokey Mountains made him hate life. He traded it the week after we got home from that trip.
Not knocking GM here so all you bow tie guys keep your panites out of a knot. It does not matter who makes the truck, 3.42 or 3.55 gears are not meant for towing. Especially real loads in tough terrain. 3.73 or 4.10 gears are what you need in a truck. No matter where you get the trailer you are going to struggle with it even if its just for 100 miles. Sounds like the last 100 miles are the toughest part of your trip and not having the proper gearing is a big problem no matter what type of truck or how much HP you have. Trust me, been there done that with a 10,000# boat and a F-150 in the Smokey Mountains on a 105 deg day. The truck would not make it up a paved road without the use of 4 wheel low. In 2 wheel drive and 4 high I stepped on the gas and it would not move. Only other time I have seen this is with my buddies 2500HD GMC with the 6.0 gas engine on a boat ramp and the boat in my avatar.
