Good day: We are new to this forum and we are presently researching the potential purchase of the 2021 Chevy Trailblazer LT. to tow behind our motor home. We have read that in order to tow the Trailblazer 4 wheels down and to avoid discharging the Trailblazer battery while towing that the Owners Manual provides that the negative battery terminal should be disconnected. With the battery disconnected, how does the rear taillights on the trailblazer work i.e. brake lights, turn signals, etc? Is it possible to keep the negative terminal in the trailblazer connected and run a charge line from the motor home umbilical to the tow vehicle for the rear tail lights to operate? Thank you in advance for your respective responses.
