I have a 2003 2500 v10 all stock and getting 10 mpg, does anyone have any suggestions to help increase mpg? I hear about alot of options but would like some input from someone that anything really worked or if just hype?

there really isnt much to do to get better mpg's. things that do help, only help very minimally, and end up costing more than the better mileage will offset. things that come to mind though are e-fan, gears, and driving slower. i dont know what is available to you v10 guys in terms of tuners, but those will show a little improvement as well.

Yeah, I don't think there is a whole lot of room to see any substantial gains out of that torque beast, but you might try to post over in the 2nd Gen Ram section where a few guys have that engine, they might can give you a tip or two to eek out a little bit more mpg's...
Sadly, the V10 never really took off as far as getting aftermarket support, I always liked it, or at least the idea of it as a nice niche for those without the funds to purchase or wanting the upkeep costs of a diesel, but still needed a haulin', workin' beast...
I had a 97' that got 12-13 pretty consistantly. It got 9-10mpg when I bought it, but new plugs and wires got 1 mpg, k&n air filter gained almost 1, and cleaning out the air pump filter for the catalytic converter gained another 1 mpg. Doing doughnuts around my mom's car dropped the mileage about 80% and cost me lots in gas and tires, but man was it worth it! I like my 03 hemi that gets 13-14mpg just as much as the 97', but the v10 was paid for and you can buy a lot of gas vs. getting a "more efficient" truck like I did.

I just bought a '99 Ram V10 - 4.10 diff. 4X4 - Auto. Only 81,000 mi. The digital display goes to 8.5 - 10.5 and once 11.7 driving back to El Centro from Phoenix. 0-500 ft. elevation. I just manually checked mpg first time. 155 mi. , 27 gal. Only 30 mi. while pulling my 10k lb trailer. I am getting 5.7 mpg ! I do have 2- 90 in. toolboxes on the top bed sides and a coupe bins for more tools totaling about 800 lb.
What this proves is that the digital calc. is WAY OFF! I see in all the posts about mpg that no one mentions if they are just looking at the digital display. Using 9.5 vs 5.7mpg this is a 40% discrepancy!
I replaced my '97 f-250 - 460 gas which got 8.5 - 9 pulling. 3.55 diff. ( w/ 1,400 lb service body and topper plus cargo.)
Well, I wanted more power as I live on the road pulling my house. (As little as possible) . I cancelled getting the diesel because of potential huge parts-maintenance costs.

Reason: Weight factor with tool boxes added and % difference.
