We have an 04 Holiday Rambler Vacationer. When the brakes are applied, the tow dolly lights don't activate. All other lights work, including the flashers. I called Monaco and they couldn't come up with answer other than a converter box isn't totally working. Couldn't give a specific location of this box other than inside the front bumper. I looked around and couldn't find one. When hooked up to our car, all lights function properly. I Would appreciate any suggestions on the issue.
