Since you installed new tail lights, do they have a separate ground wire?
Some tail lights just depend on the mounting bolts to establish a ground contact with the skin/siding of the RV. If you have no separate ground wire and your RV skin is non metallic, then the mounting bolts `will not make a ground. To test this theory, attach a jumper wire to a frame/ground point and touch the other end of the wire to an exposed metal part on the inside of the tail light thus making a ground connection and see if the lights come ON. give it a try.
