cavie,
The reason for the need for protection on 50 amp is because of the possibility of an open neutral which could feed 240 volts through one leg of the RV frying lots of items.
The risk of that happening on 30 amp is far lower.
Check polarity and check voltage under load.
My configuration is (only) surge before autoformer (actually in parallel), then post autoformer limit demand to 24 amps. If more amps are needed, I switch on the hybrid inverter/charger.
