The worst thing I have done in my D3 in 2013 was turn my inawise tyre pressure monitoring system off for 10 Min to charge the iPhone on the Gibb river road, to go to the store to do an email! Lots of hours and a few minutes and a puncture and a $400 tyre stuffed. Save one tyre from destruction i.e. be repairable and you have paid for the system.

I did have some problems with valve generated slow leaks so it was still monitored but not perfect.
