Gotta hook up the sway control - some say that helps with fuel.
I don't think that will help with fuel economy, that is all about safety while towing . . . .
The fewest number of steering corrections to maintain lane-centeredness is a DIRECT fuel economy advantage. Argue it with either CUMMINS or KENWORTH who both cite it as problem to correct. Risk minimization is the mantra . . and drivers who are tired from correcting the steering also lose the fine motor skills which are the hallmark of fuel conscious driving.
It's rather nice how safety and fuel economy go hand in hand. Same for a strict observance of the rules of the road.
Fuel economy is all about the small things. Lowered speed is easy . . but only a beginner step.

"The fewest number of steering corrections to maintain lane-centeredness is a DIRECT fuel economy advantage."
What kind of steering corrections are you talking about? I find it hard to believe that the ever-so-slight steering wheel adjustment I normally do while driving has much measurable effect on fuel economy. Maybe for an over the road trucker after a million miles or more, but just driving a couple hours to a campground a few times a year?
Number of corrections per 100-miles (to maintain lane-centeredness).
Steering gear slop, worn front end, bad shocks, live axle, recirculating ball gear box . . all are hallmark of less-than-ideal design + wear. Add to that incorrect tire pressures, alignment problems and incorrect WD hitch adjustment. The trailer can exert its own influence with bad bearing and brake adjustments, alignment, worn springs, no shock absorbers, etc. And starting with high COG, leaf sprung axles, non-aero design, poor balance FF-RR or side-side, etc.
This is before we get to winds -- natural or man-made or both -- then broken surface paving, ruts, etc. Traffic. And so forth.
Steering corrections, small and large. Some vehicles will travel a considerable farther distance over 100-miles than others. Snaking down the road.
IOW, it is worth being painstaking about all the above. It all has an effect. Fuel economy is about the small stuff once a given vehicle combination is joined (past climate, terrain and driver skill).
