Although I have a 320RS, I’ve only located the switch once and never used it again. I’m not 100% certain, but I believe it’s in the battery compartment. I know it’s not somewhere that makes sense, like the control panel
Unless something has changed, the 320RS didn’t come with the “In-Command” control system. And from what I’ve read, that might not be a bad thing. Seems like the early versions of that system had some major problems.
And congrats on the 320RS! We love ours so far, no major problems, just a few minor ones here and there. Let me know if you need any help on other features of the 5th wheel.
