Fuel mileage still sucks

[GhostHauling]

So my two cents is. That truck is capable of easily 7mpg but pulling sand boxes as I’ve been there done that in Wv/Pa/Oh short runs + lease roads but up here allot of mountains my trucks would always be averaging 4.0 to 5.5 which is normal on trucks with 550 & 600 hp with 4.11 rears & 18 speed transmissions in these hills off road oilfield work but down there I couldn’t imagine it would be that bad but still don’t think you’d be getting the best. I’d ask some of the other sand haulers you run with in similar trucks what mileage there getting and know exactly what the best mileage is for what your doing. And lastly fuel mileage can be a big indicator of serious issues with your truck but sometimes you’d lose power as well I don’t know your situation but I’m guessing by the work your doing coupled by hauling ass which at least up here is the only way to make money pulling boxes in the oilfield is the cause and going super slow In that line of work probably won’t raise your mileage enough to cover the loads lost. When I got my truck I specifically said I won’t take it in the oilfield unless it starts paying the 14k a week it used to because the wear on the trucks is significant which is why I pull a flatbed and leave the oilfield to the trucks Specd for it.
