For one day trips with a good strong battery in your towed vehicle, no you should be fine. I have experienced a dead battery on a very long 2 days of towing without driving or starting the car.
We do carry a system that ensures your tow vehicles battery stays fresh while towing. See the Toad-Charge system --> http://www.rvupgradestore.com/SearchResults.asp?Search=toad+charge&Submit=
