Interested in buying a plug-in hybrid, but you need to be able to tow a camper or a boat? You are in luck because there are several PHEVs out there that can tow 3,500 pounds or more. And if you need to haul an even bigger load, you'll be okay there, too, as long as you pick one of the PHEVs from this list that can tow 5,000 pounds or more.
