Sounds like a computer glitch within system. Need someone to do a live data analysis to determine the cause.

In normal mode, it calculates your distance to empty using the last 500 miles of data. In towing mode, it uses only the last 60. If your mileage for the last 60 miles was better than the last 500 when you switch, it will show a higher range. It will even out once you'e driven for a while.
