I have the same setup and haven’t had my battery discharge nor do I charge it while towing. Longest tow is for three straight days.I normally wouldn't disagree with Grant, he being Bronco flat tow royalty and all (seriously, not being sarcastic) but I wouldn't think you'd need towed battery charge. I have a 2.3 with vacuum assist, but the end result should be the same. I use an RVI brake with a compressor that cycles every third brake use or so and have never had a battery issue with the Bronco or previous Jeep. If you're using a 6 or 7 wire plug I'd say go ahead and do it, but if 4 wire (like me) just for lights, don't bother.
Note: I said every third brake use, I mean every third time the RVI brake engages which is seldom in a normal stop. It only engages when I am vigorously braking.
