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.

I know there are a few members here who tow behind their motor home, so hopefully they'll reply with some answers. One thing you could do is use a solar panel in the windshield hooked up to your OBD2 diagnostic port under the dash. This will keep a constant charge on the battery to prevent battery drain and wear. NOCO has a few different connectors for hooking up a dedicated charge cable or temporary charging. I have many of their products in use all the time and they are great quality.

A search for "towed" will give you some casual reading. With the battery disconnected and the lights properly wired, the towing vehicle will power the lights.

Both the power steering and the brakes are electric assist. You would have serious stability issues flat towing with these systems active.
