Unless you have a 12 volt TV, it won't work on the battery so that shouldn't be an issue. Bring a portable radio. Keep the tow vehicle running while you put the slides in/out and that won't run the battery down. Keep as few lights as possible on, and remember that your refrigerator uses 12 volts for the control power even when it's running on propane. You should be OK since the tow vehicle will recharge the battery as you drive each day.
