Thanks for all of your responses! My husband has informed me that we have a 2500 HD, not a ½ ton ??. We have a vortex 6.0L V8 gas engine, 6 speed with a 410 rear axle. We have 20 inch wheels with a GVW of 9500lbs. It doesn’t have OD, but has a tow haul button. Do most people use this when pulling their TT on the highway? I know my husband uses it when pulling his enclosed trailer in town. We have been driving about 63-65 MPH, so maybe we need to keep it around 60. I really appreciate all of your help! We plan on traveling quite a bit this summer, and with 4 kids we want to save where we can. So if we need to drive 60, that’s what we will do!
