I have a 06 6.0 250 and have a question about the tranny. For the last 15 years I have been driving tractor/trailers moving the Airforce and have always found the manual better for towing. I tow a 33ft keystone trailer and pull it fine with my auto but dont know how the manual feels. I also miss shifting and don't mind traffic. Any one have input on a SD w/man tranny.
