I'm looking at a new Ford 350 Diesel dually 4x4 to replace my old similar truck. It will tow a 13,000lb Alpenlite fifth wheel and be general transportation in the NC mountains.

Our current truck, a 94 F350 Dually Diesel is a 5 speed manual with a 4:10 rear. The new one we're looking at has a 3:70 rear and auto trans with the new Powerstroke Diesel.

Is this adequate for our needs or do we need the 4:10? I'm told we will notice little difference with the automatic and should not worry about the 3:70.

Would love to hear your experience with this. Thanks.

 

I like my 3.73's, but I don't tow 13k, boat's only about 5200. Should get better empty milage with the taller gears.

Is your engine an IDIT?

The engine in my 94 truck with the 4:10 is an IDI Turbo I believe. Is this much of a difference?

Nope, '01 Powerstroke
