Well whats so heavy about a ram vs a durango? The durango does have more
body then the ram, and you must remember that passenger vehicles are geared
more for driving then the way trucks are geared for pulling heavier loads.
It all reverts back to what they put in the gearing and what the final tire
diameter is of the vehicle being tested. Just because you run 35's, doesnt
mean you have to get 5 mpg, there is always something to help you, change
the gears to 5.xx and at least go back to double digits maybe high teens..
Its all in what you want... If you run 35's and keep the stock gears you
will eat gas, whether you have a 4 banger ina zuki or v10 in a ram....

I was by no means trying to start a flame war. But if I read it right a guy
was getting mid 20 mpg in a Ram with the 5.9L and I've just never heard of
5.9s getting out of the teens. I'm glad to hear that at least one person is
getting 20 out of a durango but I was just wondering about the mid 20s out
of the Ram 5.9L. I love my V6, reasonable power and low 20s on mpg on the
highway is nice, upper teens in town. Like i said, not trying to start a
war, I just don't see a heavy ram, pulling mid 20s with a 5.9L.

Here's the sentence I was interested in:

"I have a friend with a late-model Ram club cab with a 5.9L and he gets
mid 20's out on the highway it's embarassing.
If any one is looking to buy a Dakota, AVOID THE 3.9L at all costs!"

I agree, I had a 97 Dakota SLT 3.9L automatic, stock tires. Not sure the
gear ratio in rear. When I bought it I ws getting 17 highway. Installed
K&N homebrew, free flowing muffler, 3923 plugs, and homemade tonnau cover
and went to 21 miles per galon on the highway. Now have a 2000 Durango SLT
5.9L automatic, stock tires. Not sure what I started with but did the 3923
plugs indexed, K&N drop in filter and synthetic oil in engine and get 20MPG
highway doing the speed limit with A/C going. Keys to mileage is proper
tune up, proper tire inflation, and easy on the gas peddle.
