Re: Help! anyone know the average gas milliage....

2007 classic look 2500, 4x4, auto, 285 tires, ladder rack, short box, 4-doors otherwise empty 11-12.5 with half city and highway miles. I have 108k miles on it in three years. pulling 10k trailer 5-6 mpg (26' weekend warrier toy hauler). I had the same motor in a 2006 extra cab 2500, auto, 2wd with the stock 245 tires, it got 17mpg empty and got 9-11 towing a 10k gooseneck dump trailer.

It still runs like a champ, never an issue. Just oil and filter changes every 90 days. Truck shown in background of picture.
