I have a 95 2wd dually w/5 speed stick w/3.55. Pulling a 32ft tri-axle I get 12-13 at 65mph. It has a #10 cam plate & 4" exhaust. I put 285 tires on the rear to lower the engine speed ,it didn't help much. We've had this truck since new. When it was stock pulling a 28ft trailer milage was about the same. Sure would like to see milage like Mr P.

This is the reason I get better mileage(the trailer).
I have a 6 sp in mine over the stock 5 sp and the 4"
exhaust, I have a #8 plate that I'm going to put in
in the spring. Once I'm on the xway my mileage is good,
its getting to the xway that it sucks.... city stop
and go trafic KILLS my mileage. I put the taller
tires on also to help the gear and it helped a little
but I still wish I could lower the RPM even more.
I tow at 2000rpm and no higher than 2200rpm
