 Towing speed
We usually tow as close to 1600 Rpm, approx 58 mph, using overdrive in our '03 Dodge 3/4 ton PU. It has a Cummins diesel and we've found that we achieve our best mileage at that combination. We'll average almost 16 mpg overall on a 1500 mile trip. With level highways and a slight tailwind we've gotten as high as 23 and as low as 13 in the mountains. We tow a 31ft '84 Excella and have gotten approx the same performance towing a '96 25' Classic. It really is interesting to watch other rigs fly past us and then find them just ahead of us when we pull into the next fuel stop, etc.
I used to think I had to travel at or near the posted limit, but have found the past two years that I am now more relaxed and appreciate the lower fuel costs. Dean
