Biggest you can get!
Years ago when the batteries in our 2001 Ram started to fail I came home from a 5 day trip to dead batteries at the airport parking lot, they sent a little Ford Ranger took about 20 minutes before it gave enough of a charge to start the engine. Keep in mind this was with mechanical injectors and a an electrolyte/mechanical pump engine only needed to make one rev to start.
