What MPG value does the truck use to calculate Range to Empty? I have noticed that the Range to Empty can change rapidly after unhooking or hooking the trailer. But it doesn't seem to be tied to the Fuel economy screens or the MPG on Trip A or B.

I keep a pretty close eye on MPG and it seems to be tied to an average of the last X miles. What that number is, I don't know.
If I'm towing something, it really takes a hit and takes a bit to recover. If I'm not towing, it will slowly crawl back up.
I've been doing a lot of highway running, travelling for work lately. Last fill up damn near had me at a projected 600 miles for the tank.
