We have been RVing for close to 20 years. We buy the individual surge suppressors that plug into the wall socket. We have them on every plug that has something with electronics in it. Microwave, TV, Fridge, etc. Once in 20 years we had a surge which the small individual ones worked. They take up no space, no need to secure them, and work with any AC power, shore or gen set. About $10 @ Lowes
