This topic is different for everyone opinion, so let me put in my 2cent worth. First I have towed with all towing systems. Presently I use the magnetic lights on my present auto. I feel it's the best for me, it's quick and easy. Don't have to worry about feed back to the motorhome electrical system or running down the battery when it's raining or driving at night and your running all your lights. All I did was installed a connector just below the tow bar attach point on the auto next to my air hook up. Ran the wires to the back bumper leaving the connector on. I them place the lights where I wanted them, ran the wire to the connector. I then made the connection, since I had some much wire left, I opened the individual light cut the wires shorten them to the proper lenght. So all I have is a short wire on the lights. When I don't tow I place them in the space tire compartment. Out of sight, Out of mind.. I had my Saturn wired into the electrical system and towed it for 4 years, had to pull fuses before towing and still had a ended up with a dead battery at the end of the driving day. The magnetic lights work well for me.
