On a road trip, in a large vehicle with a huge Cd, your best bet is to inflate the tires somewhere between factory spec and sidewall max, use the a/c on recirculate, and drive at the speed limit, tailing a truck by 5+ car lengths for safety.
P&G is not advisable for an automatic transmission, plus you have to use the starter to restart the engine, which uses lots of electrical energy that must be made up by the alternator. In a manual, you can bump start and eliminate damage and electrical losses
