If I were to guess the relay may be used to isolate something from the house batteries. My original coach had a single 50DN and it charged both house and chassis batteries, but it needed to have alternator output to a heavy duty relay to close the circuit between the two for charging.
I suspect you charge the chassis via an alternator smaller than the 50DN so that is not its purpose. But something likely does not get 12VDC power unless the alternator is charging. 75 amp is big enough to handle one A/C through inverters while driving because they use about 65 amps on 12VDC.

I also have a long 24v Delco aalternator for chassis batteries.
