As for the Ford not being able to pass at highway speeds. I just picked up the boat Sunday. It is a 24' Larson that weighs in at 6800# boat, trailer and full of fuel (55 gal.). I tried to do a video towing it but could not figure out how to live stream it. Bottom line the Ram is running a 8 speed trans and the Ford has a 10 speed. With all of those gears these little diesels do not have any problems passing. At 65 mph I put the go peddle to the floor and before I was half way around a big truck I was at 82 mph. This is with a 8 speed the 10 speed will or should do as good.

Gears only multiply torque, not horsepower which is what dictates how fast you can go passing. The difference between a 6 speed and 8 speed attached the the same engine in regards to passing power would be almost identical or very minimal. What an 8 speed will gain you is the ability to stay within your engine's peak power range better than a 6 speed especially when towing.

There can be a big difference depending on where the two extra gears are added. In big trucks the difference between a 13 and an 18 is on the bottom end. After you,re on the high side there's no difference but you take a 10 and a 13 and then you have the passing gears with the 13. 13 on the high side will walk off and leave a 10 on the high side.

I was referring to the difference between a 6 speed and 8 speed in our trucks.
