Hello. I have a 2003 Monaco Diplomat and just bought a tow dolly. The MH has the standard round connector and the tow dolly has the mating connector. When I connected the dolly to the MH and tested the lights, the lights on the dolly only came on when the MH's headlights were on; the brake lights and turn signals on the MH did not cause the lights on the dolly to come on. The dolly manufacturer said that I need a tail light converter, which I had never heard of before. I thought that because the MH is already rigged for towing (the previous owner towed a trailer for 10 years) that nothing would be needed, other than to connect the trailer/dolly to the MH. Can someone please explain what's going on here? Thanks.
