Pete, it kind of depends on how much weight you tow.
If you read the post about my blown head gasket on a diesel and what
Chris towes with a Dodge 1500/4.7/auto vs bigger diesel truck.

So again it comes down to how much weight do you tow?

I have a 2004 Ford F350 4 dr/4 x 4/long bed 6.0 diesel/4:10 gears, when towing
my travel trailer which weights in at around 7500 lbs loaded it will get 9 to 13 mpg
depending on how many 6% hills I have to climb. My Duster on a 18 ft open trailer
falls into the 5500 lb weight catagory.

I have found out that I can tow the same trailer with a Ford F150 5.4/auto/3:73 rear
gear ratio and be fine (actually good up to 9,000 lbs).

Same goes for a Chevy or GMC V8 with similar 3:73 gear ratio will tow similar
weights to the Ford F150.

Dodge has the problem that there is nothing between a 4.7 V8 that will tow 5500 lbs
and the HEMI or Commins diesel which is needed to tow heavier weights..
