If you travel a lot, keep in mind that that 2nd engine can be used to drive somewhere to get help for roadside emergencies instead of being stranded.
Regarding the TV, a car that CAN tow that weight doesn't mean it is MEANT to tow that weight. We use my wife's Equinox, which is rated at 3500lbs to tow my boat, which is maybe 1300-1500lbs with equipment and it pulls fine, but the engine struggles so much that her mileage is cut in half from 20-24 down to about 12. My Buick Lesabre has a little bigger engine (3800 Series II) and it can manage 16-17mpg. While the dealer rates it at 1500lb capacity, it pulls much better than the Equinox. The only reason we use the Equinox is because my wife doesn't want to drive "a grandma car".
