Towing Mileage for 325/600?

[Mike Ellis]

I rode in a fellow's truck the other day, it is one of the 325/600 trucks, 4wd auto, less than 10K miles. He was not real happy with the mileage, pulls a 10,000 lb trailer / Bobcat and is only getting 8. 5 - 9 mpg while towing. He previously had a Duramax, and before that a 2nd gen 12-valve Dodge, both of which returned 11+ mpg pulling the same load. He likes the performance of the new truck compared to the other 2, but definitely unimpressed with the mileage.



Is this typical for a 3rd gen with the 325/600 engine? Based on my old '97, I would expect at least 13 mpg pulling the trailer and would have thought the newer more powerful engine would just make things easier...

Mike' I just got back from a 4173 mile trip pulling my 11,500lb. 5th wheel. I started out with 3750 miles on the truck. Heading from Carrollton, TX to Amarillo, TX in to a headwind, I got 8. 5 mpg. Going from Amarillo to Las Vegas I got 9. 5-10. 5 mpg. All this was into a Westerly wind. Overall I averaged 10. 5. When I first got the truck and driving around town it got 16 mpg and dropped down to 14. 0 before I left town. Now I'm geting 16. 5 If your not doing anything June 12, come over to the BIG D DODGE DIESEL CLUB meeting
