Surge Protector - Hardwired without transfer switch?

My new to me TT does not have a surge protector (SP), portable or hardwired. It also does not have a transfer switch (TS). I have not yet verified, but I assume the power cord used to connect my trailer to a power source (ex. power pedestal at campground) is connected directly to inverter/charger box where 120V and 12V fuses/breakers are located.

The last hardwired SP I installed was in my TH that had a built in genny. I installed the SP before the TS.

I want to install a SP in my TT. MY TT is 30amp.
Do I need to have a TS to utilize ALL aspects/benefits of the SP?
Or can the SP be installed anywhere between the power cord and the inverter/charger?

Thanks!

    Tucquala....as DrewE suggests, sounds like the bonding plug is what you and I need.

    would a bonding plug be needed on EACH inverter/generator when connected with a parallel kit (I will be using two Champion inverters combined with the parallel kit)?

    I'm not DrewE, but one bonding plug in the system is enough. You don't need one on each generator. However, be sure the bonding plug is on ONE of the generators, not in an RV outlet.
