My first question is why do you want an inverter? Are you prepared to up grade your batteries so that an inverter would really be feasible? Your coach is like my old class A the controller is all that I needed to run things with that said if you are going to a residential style frig then an inverter makes good sense. Use your generator when needed including when your are underway and enjoy.
