Am getting a new trailer. It’s set up for 50amp but doesn’t have the 2nd AC unit installed. Has the 50amp cord. Without the 2nd AC, I wouldn’t think that the RV would routinely pull more than 30 amps. My question is, can I use my 30amp surge suppressor or do I need to get a 50amp?

I would get a 50 amp then if you use reducers put them on that. when I am in a 50amp campground I still plug directly to 50 amp through my surge protecter so I can use the ac and microwave at the same time, or the microwave and toaster or what not. the price difference between 30 and 50 amp protecters isn't a lot.

also if you have a auto change over switch in the unit, make sure they install a proper 50 amp one... they pulled a fast one on me as they didn't have a 50amp in stock and it was 3 months later when it burnt out, so they had to put a proper one in for free.
