Am I getting BSed

There's a lot of things your not accounting for that would make the question easier to answer. There's weight of load, trailer type, engine tranny and gears. So no your not and yes you are being BSed. Now as a new guy here best answer you got so far.

 

Mine, 500 CAT, 15 over and drops to 50 MPH on the hard pulls. Love to catch Schneider about halfway up and blow em off the road. I can't compute "Harder on equipment" How is it harder. A truck is built to pull a load. I get the same mileage/gal running I 70, I 94, I 90 or I 80 averaged out over a year. I can't find the wear. Prove it. If it is true then, Colorado trucks won't last as long a Texas trucks? Figure in wind, weight, direction of travel etc. Never mind. Run whatever way you want but 200 miles is out of the way in the Rocky Mountain States.

 

All I know is there is an avg . Fuel consumption , if its 4 or 4.3 ect , so running 200 additional miles??? Let's say if the fuel was slightly less say .3 mpg running a thousand miles vs 1200, 1000 mi ÷ 4 =250 gal , 1200 mi ÷4.3= 279gal , it would take a full 1 mpg to see any savings in fuel 1200 mi ÷ 5 =240 gal so you save 10 gal at say 4 buck a gal =$40 but you spend 4 or so additional hours so you only make 10 bucks per hour ? Or you lose due to running out of hours for the week or it runs into another day , ?

 

If you haul potato chips out of California to Denver, you really do want to take 40 to 25 and up to Denver, if you take the 70, the bags can and do explode. I had a buddy that did just that, said his freight was a mess when he got to the WalMart DC in Loveland. I was always routed over 70 though, I usually hauled pet food.
