Yeah, you can totally set up a remote switch for the generator. I’ve got an older RV too, and I added one myself. If the previous owner showed you, there’s probably some wiring already in place—you might just need to find where the switch used to be or where it could connect. Look around the generator or the control panel for any signs of it. If you’re comfortable with basic wiring, it’s not that hard to install one yourself, but if not, an RV tech could do it pretty easily. Worth it for the convenience!
