On more question: many mentioned running a wire to help keep tow vehicle battery charged from the RV alternator system. Assuming this is since the tow vehicle ignition is on the "ON" position the whole time while traveling? So, the 7-pin hookup does NOT account for this, right? I was going to have my brother assist with this if and when I go this route, and just wanted a heads-up.
The auxiliary brake mechanism also uses electricity from the battery. On a long trip, it can run the battery down. The "hot" wire will help keep the battery charged. The 7 pin plug should have a hot wire in it.
