it is a dually has new air filter and fuel filter my 02 with the same trailer and with a bigger loader averaged loaded for about 500 miles up and down in missouri 12 mpg went to wichita with his yesterday with my loader and the trailer he got 8.5 loader pretty unhappy with the mileage but runs excellent performance you cant complain about guess you cant have it all oh well its not my truck:lol3:eelout:hyper:
