What's the fuel mileage from before and now.

Same roads same loads, i drive the truck 5 days a week, run alot of the same routes at the same weight. The fuel mileage never changed much it will average 4.2-4.5 loaded both ways and its a car hauler so thats pretty normal fighting with wind all the time. You just have to stand up in the seat and cuss it up hills alot of times even on regular interstate hills you may be running 35 at the top of some and im not talking about mountains. I aint interested in it being a dragster but id like for it to maintain on small hills
