If you have a 30A entrance and service panel, a power surge is possible. If you have a 50A service panel and entrance a power surge is also possible, and- other electrical issues come into play. If the neutral is lost in the CG service wiring it can input as much as 240VAC to your RV. This will destroy anything connected to that feed. Read this and it might help with my explanation:
RV Electric
From the left side menu you may view 30A wiring, 50A wiring, CG wiring, etc.
I regret your first use of your new 5er involved such an incident. You might consider buying an Energy Management System to prevent future electrical issues like that. One such EMS is Progressive Dynamics

They make the hard-wired model as pictured, and a model that plugs between your power cord and the CG pedestal.
