Pulled a 14,500lbs 5th wheel for 600 miles....
Got my totally stock f450 dually and left to Reno to buy a 14,500lbs Toy hauler. Truck did great, averaging 7mpg combination steady 4% uphill pull and elevation of 4,500 to 6200ft above sea level (overtook an anemic new looking Dodge with a much lighter RV). Yeah, it is ****ty fuel mileage, but oh well! One thing was quite interesting....I was hauling my toy hauler up an 8-10% grade for about, oh, 120 yards and everything going well when suddenly my 6.4 had a sudden new sound......sounded like a distant muscle car at wide open throttle. I looked around and was looking for a Mopar Hemi, or a Ford 451 cleveland...but I was the only one there. I let go of the gas pedal and the sound went away. I thought....what the hell was that?? No power loss, just that low grunt/rumble. Anybody with any ideas of what was going on??
Need to do something about that ridiculous low fuel mileage!
