First time that I'm overweight on drives and tandems

5th wheel forward more on the steers.

 

So, if diesel fuel weighs roughly 8/lbs/gallon, and you get 12 mile/gallon, you lose 2lbs every 3 miles on mostly your drives. You still have a minimum of 1,100 lbs to send to the steers, too. I'd move the 5hth wheel 1 notch forward, maybe 2 of you have a scale nearby. Or.....you can rum back roads for the next 750 miles to be safe....

 

Diesel is closer to 7 pounds per gallon unless it’s pretty dirty.

 

Good lord run that!

 

It's sort of like running 5 mph over the limit. You could technically get popped, but it's more likely you won't.

 

12mpg?! What world do you live in? Maybe 8avg if it aint hilly.

Rotfl 12mpg.

 

Really? I was averaging 11 in 1990 with an L10 motor.......

 

I’ve been driving trucks for 8 years in 5 different trucks and the best I’ve ever seen a truck make is 6.4 mpg.

 

Run it

Our Volvo 860 may get 12 mpg if its bobtailing on flat ground. Loaded @ 78k we will be at 6.5
