Tail lights messed up

I have an 87 RV on a J30 truck chassis. It's a "two light on each side" set up. When the headlights are on everything looks ok in the rear. Hit the brakes, the top passenger light "brakes" and the lower driver's side "brakes." Then you put it in reverse and only the driver's side "back ups" come on. There is an after factory back up on each side and only the driver's side lights function in reverse. Checked and replaced all the bulbs. My thoughts were someone monkeyed with the wiring when they bought a tow dolly. Your thoughts?

I think you were very close when you said;

"My thoughts were someone monkeyed with the wiring when they bought a tow dolly"

I would start there, check out the wiring. If all of the bulbs are in the correct sockets, and oriented in them the correct way, it seems that the wiring is not correct.

Good luck, post back and let us know what you find out.

You may also want to check and make sure you have a good ground on the lights. A bad or no ground can cause all kinds of problems with the lights.
