Is there actually a 15 min tow time limit in towing power mode? If there is a time issue, presumably you could start the APU, Would that work?
Reading through this thread, there does seem to be a lot of opinions and guesses that later somehow become facts because "someone said it" earlier. I know it's just a rumour forum in which anyone can post but unfortunately it's easy for something that sounds clever (which was just a guess) to get taken up by others.
It would be helpful if posters background and relevant experience and qualifications appeared next to their posts on technical issues.
