READ your tow vehicles manual first. If the TV was meant to tow anything, there will be a section there describing towing. Even within the same brand of vehicle, there are different recommendations depending on the TV(PU, SUV, CUV). Some will tell you to tow with the OD on, some will tell you tow with it off. Some will also tell you to put it in tow / haul mode then either turn the OD on or turn it off. Do what the manual says!!!!! You may need to add a transmission / oil / and or power steering cooler for towing, but that is a different question. When in doubt, follow the manual.
