Default Re: low fuel mileage

Hi Guys,

Took a long road trip (Topeka, Indy & Earlville) from Northern California to Indy and back, which totaled 6100 miles.

My tow rig is a 1999 Dodge Ram 3500 CTD with DRW, 5 speed (now 6 speed) 2 wheel drive, 3.55 rear gear and a 28' Pace Shadow trailer with a combined loaded weight of just under 21,000 pounds.

The trailer is a tag with no additional height which helps keep it out of the wind.

The only non-stock items are a 4" exhaust, exhaust brake and a K & N air cleaner element.

Driving at 65 mph most of the time we averaged 13.1 mpg for the entire trip. I think that keeping the trailer low enough that it's out of the wind is a big help to the mpg.

As an added note the change from a 5 speed to a 6 speed, later on was a welcome addition to improve the driveability of this truck while towing.

My truck now has 224,000 miles on it and still gets right at 20 mpg not towing

Just my 2 cents,
Bob

PS:
Now to find the quietest straight through 4" muffler made.
