Jamie, I'd like to know how they will measure improvement when the chassis and house are built by two separate companies. Ford could make the chassis 10% more efficient and then have a larger and heavier RV built on it by others, offsetting gains. Does rule apply to chassis or completed motorhome?
By the way, the Ford 6.2-liter V8 as tuned for 2017 Super Duty has excellent power and torque ratings. I doubt too many will miss the 2-valve V10 in their Axis or Class C. That revision alone should make a significant difference in MPG.
