Thus, I wouldn't see a need for a transfer box.
It might be worth a call to Coachmen to verify.
An automatic transfer box just makes the transfer from gen to shore power automatically. It will connect to the generator normally until you plug into shore power then the transfer box automatically switches to shore power.
It's a must have for me but others will disagree. It's raining and your shore power kicks out for some reason, I can start my generator and have power immediately, no going out into the rain to unplug from the shore pedestal and replug into the compartment receptacle.
