Marshall auto switch over

My SOB brand trailer had a Marshal Automatic Switch over valve and I had a remote inside my camper that would blink when one of the tanks went empty. I sure do miss that.....Mabey I will change out the one that came with our Big Country.....

I'm with you on this one. I haven't use a tank of propane yet but the regulator looks like it is half red already. I hope I can tell when it is out because I leave both tanks open.

They sell this clip-on indicator light accessory seperately, but you would have to route the wiring. http://tweetys.com/remote-changeover-indicator.aspx
