Two years ago we were camped in a full hookup in Wash St. Stupid me, I put my surge protector away to get a early start the next morning. Not 5 min later we had low voltage and in just seconds it took out my ref, a/c/ heater. I sold my TT because of the cost to replace. Now I wish that I kept and replaced them since I cannot find a front kitchen with 14 ft slide and under 34 ft. I highly
recommend surge protection !!!! This was the first time that I ever had anything fried in over 55 years of camping but that's all it takes
