Yes I have a simliar generator door on my Wolf Pack and I replaced one of the factory knobs with a cam lock. Instead of putting the built in Onan on my unit I opted to buy a Champion inverter generator. I can carry it in the original generator compartment, but when I'm not camping or during the winter it's in my home garage in case I ever need it. A lot cheaper than the Onan and serves multiple uses for me.
