Totally Agree with RichPatty. If you have a seven pin connector there is a constant power pole for electric brakes that you can tap to attach on board charger to. That is what we do.There is a constant draw on the battery while it is being towed and if the battery was weak, it would enough to push it over the edge. I know from experience. Especially if you had been towing it for more than one day.
I would look into putting in a charge line…. Which would give the car a trickle charge from the RV.
thanks, I will be ordering one of these, $165.00 is pretty cheap insuranceThey also make products specifically for this…. They don’t make the one I have anymore, but this one is similar…

Towed Battery Charger Plus for flat towing
RVi Towed Battery Charger Plus, charge line replacement for flat towing a vehicle. Great peace of mind for the towed battery while towing a car behind a motorhome. Often used with RVibrake. TBC+rvibrake.com
That’s the unit I have. I am just starting to flat tow and the charger has worked well so far.thanks, I will be ordering one of these, $165.00 is pretty cheap insurance
