That's a very nice rig I would think it would come with an automatic switchover regulator, handy device to be sure. For those that oppose having an auto-switchover for their propane tanks, simply leave second tank valve in off position and when you run out of propane in first tank no changeover occurs. I do this during the warmer months but when we camp in frigid temps I utilize auto changeover as I prefer not run out of propane overnight.
