I have used both the Progressive Industries and the TRC. Both are good. One time I was plugged into a friend's house (this friend had a special RV hookup installed for me) and I foolishly ran the water heater AND the A/C both on electric. I was using the Progressive Industries Surge Protector. OOPS! Running BOTH those appliances exceeded the 30 amp load, and I fried the surge protector, fried the cord, but his plug in is still good! (it was 100 degrees out that day) Let's just say, this surge protector saved a friendship.
JJ only, my cat went to Rainbow Bridge July 2015
I love my Sunseeker, when I'm on a trip I don't wanna go home!!!"
Total days camping each year: AS MUCH AS POSSIBLE!
