Thanks for the response Gdetrailer! We looked into the option regarding the inverter with the transfer switch/built in charger. We already have an inverter though that does not have the internal charger/transfer switch, and don't want to put out the money at this point. We may switch to that in the future, but currently want to stick with what we have. The cam switch is a cheap fix in the meantime. I'm curious about what you said regarding the cam switch rating. I went with what the OP in the linked post went with, but I can choose a different rating.
