The only lights not working are the RV's tail lights, brake lights and turn signals. The side markers, front lights/signals and clearance lights all work. The only thing working on the rear of the RV are the backup lights. Everything works on the toad.
I'm going to look at a few other things then call in a repair person.
Forest River tells me it's not a Ford problem but a FR problem.
