If your Tioga is like my Jamboree the grounds in the rear running light are via one of the two threaded studs that hold each light in place. I would remove each lamp and clean the stud amd mating surface in the lamp and see if it improves. It might be a good time to replace them all if they are the original lights. They are relatively inexpensive. The grounds are wired in series so a difference in voltage often times is linked to a bad gound connection somewhere. The positive connections are in parralel however.
