has anyone installed the Camco water heater coversion kit

. . .I built a T for mine so that I could have BOTH the heating element & sacrificial anode in my water heater; works GREAT as long as you are plugged in. . .I USUALLY boondock / hit areas without electricity available, but, when I am plugged in it works as advertised. . .Also, the water heater mfg. would have to prove it caused the failure of the tank, and, how many times have you heard "the water heater failed" on a well kept RV???
