As far as the shifting goes, I guess you'll just have to wait until you get to the pump to find out for sure. I've learned shifting is kind of a habit thing--once you've done it one way for a while it takes some concentration do adjust your normal routine. Let me know how it turns out.
I'm quite confident the mpg will have improved, that is almost beside the point for me in some ways. I really do need the U-gauge (or similar) to tell me about shift transitions. As to driving changes, I'm in Direct just before 30-mph now. Before I was simply using rpm to guide shifts, as in, a working range of 1,700-1,900 rpm which told me (based on a number of factors) which gear to be in. Even if I was running 33-mph in a 40-mph zone. Now, just keeping rpms as low as possible and an even lighter foot on the throttle . . it's too easy to lug the engine. Granted, a V8 Ford or GM would have a time of it, but even an L6 CTD can pull down too low at times (for my level of comfort).
That level of comfort has to do with always thinking of the truck as loaded, and towing so as to keep shifts and other driver inputs or motions consistent no matter the actual configuration. The "habit". I dragged a 7k trailer back to the house the other day and was pleased that so little change was needed in re shifting, throttle work, etc.
Solo miles may rule, but they don't pay the freight for what the truck is best at doing, it's raison d'etre. Longevity first, reliability second and FE a rather distant third. But TEAM CUMMINS done got in the way, so . . . .
Thank you for sending the Excel file at your convenience.
