I gave my 3912 raptor a progressive industries surge protector for Christmas. it tells you your volts, amps, and possible errors in voltage. I recommend it for all rv's but especially those of us who like bike rallys. lets face it most of the FUN rallys have crappy power. it is a good peace of mind to add one to your rv. I was at little Sturgis last year and we were running 140 volts per leg. I decided to add one. I love the remote display. its worth it
