So, when should you run in tow haul mode.
I pull a 20' boat behind my 2500HD and it really has no problems what soever pulling it at any speed. The only thing I noticed in Tow Haul mode is that it runs at slightly higher RPMs.
I think the boat and trailer runs aroun 3000 lbs. Should I run in tow haul mode with it or just when running my heavier (over 5000lbs) office trailer?
