30amp surge protector on 50amp line

Quick search here turned up nothing.
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?

    The Sola Basic is listed in my signature.

    It is able to handle 4000 watts--which makes it a great match for a 30 amp RV. They do make a unit that has two legs for use on a 50 amp RV, too--but I don't know the specifications.

    I use it a lot in cold weather to get the most from my electric heaters. As you probably know the power varies by the square of the voltage.
