F-250 Towing Mileage Reduced by 25%
I took my 2015 F-250 4x4 6.2L V8 and trailer out for the first time this year. Truck has 15,200 miles on it and it is due for an oil change and tire rotation (right at the 5,000 mile mark). No check...

On both vehicles:
Alignment
Brake drag
Tire pressure
On TT:
Bearing preset
On TV
Fuel & Air Delivery
On lash up:
Set WDH at CAT Scale. Obtain good numbers using three pass method. Use this as baseline. I've seen changes of 20% after rectifying.
As to testing:
Use crruise control for consistency. Avoid lane changing, and keep speed below 64. Commercial traffic moves at this speed and higher. Don't mix with commercial traffic or today's ultra-idiot four wheelers.
Be very consistent trip to trip.
