The other issue is a manual tranny hurts mpg in most cases. What I mean is you can drive it how you want with a manual but a auto is much more consistent delivering consistent performance.
My mechanic drag races. He has a Mustang with a 4.6, nitros, super charger, ect, ect, ect. Its a fast car. Anyway it came with 3.55 gears and would run 12 seconds to high 11's. He swapped the rear to 4.10's and guess what it runs 12 seconds to high 11's. The 60' and 1/2 track speed is much higher but the end result is the same. He keep the 4.10's because its much more fun to drive.
Fast forward to the next year. The car was a Auto. He swapped it to a manual and lost speed. He let others make passes in the car and they could not match the speed of the auto. Granted the auto was built up with a good torque converter, shift kit, ect. He put the auto back in and the times came back down. Still runs the auto to this day. Just goes to show you that a modern auto is very efficient and will provide the best performance overall.
I agree, for towing, especially what I do there is no way I would have a manual. I could not imagine 15,000# to 25,000# behind my F-350 on a slick steep boat ramp with a manual. Even in 4 low it would be next to impossible to not smoke the clutch.
Dodge is the only one currently offering a stick in trucks. The last time I looked at them in 07 they derated the engines in the manuals versus the autos. I wonder if this was done to keep the warranty claims down and the clutches in them? I am sure Dodge and a manual tranny is soon going to be a thing of the past.
