Setting up Chevy Equinox for flat towing

For a follow up, we completed our trip and returned home this weekend. The first leg was a 10 hour drive from Florida to western S.C. I had the #32 fuse in the cabin fuse box left in and pulled the #16 fuse in the engine bay fuse box (this is the "new" way after some people had a death wobble experience pulling the #32 fuse, which leaves the electronic steering not energized). I also left the vehicles tail lights in place, hoping the charge line would keep the battery charged. After driving for several hours and stopping for gas in the motor home, I started the equinox to circulate the transmission fluid. It started, but sounded a little weak at start up. I drove several more hours, and at the next fuel stop, the battery was completely dead. I pulled the tail light covers and disconnected the bulbs and jump started the car to let it run for a few minutes. The next stop was our destination in S.C. The car started, but again seemed a little weak when starting. The next day we continued on our next leg of the trip to middle Tennessee. At the first stop, the battery was dead again, even with the tail light bulbs pulled. I jumped the car again to run it, and then we continued on to our campground in TN. So, after camping for a week, I knew when we left to come home I would have the same situation if I didn't change something. So I decided to try the "old" way of towing the equinox by leaving the #16 fuse in and pulling the #32 fuse and taking my chances with the death wobble that some have experienced. It worked great, no death wobble and no dead battery. I don't know why it didn't work the first way, when I checked the charge line it was putting 12 volts to the battery from the motor home (I have no idea about the amps though). One thing to note, our car has the built in wifi system, so it is using whatever volatge is required to power up that system. I don't know what else would be causing the drain other than possibly the electronic steering system being energized with the #32 fuse left in? Anyway, I will continue towing with the #32 fuse pulled and take my chances with the death wobble, which sounds like a rare occurrence. Thanks for any responses or info.
