We put 47K tow miles on a 2013 CRV., with a Ready brake tow bar and the fuse bypass switch. In three years of hard use, I killed the battery once, by towing it for a full ten hour day, without flipping the fuse bypass switch. And once by parking on a very steep slope, facing downhill, and forgetting that the brake lights on the Honda were on, because the ready brake was still pulling the pedal down. I swapped the '13 for a very low mileage '14 recently. I eliminated the hard wired tailights, and switched to wireless, magnetic LED unitson the "new" car. That has eliminated the biggest PITA of all, which was continual issues with the toad lighting, usually caused by the cheap, Chinese piece of trash six pin receptacle mounted on the car.
