This. At least my Jayco Redhawk 22J has this.
There is just one entrance for water, where the city water fill is. Inside the rear compartment are 2 "switches". Each one has 3 positions. Depending on the source of water, the valves are set to different settings. I have several choices. 1) city water, 2) fresh water tank fill, 3) country fill (for pumping water from say 5 gallon containers to the water tank), 4) normal (using the water in the fresh water tank), 5) winterize, 6) sanitize.

I assume you looked around on the exterior and didn't find a fill hole?
If you don't: You could stop by the hardware store and pick up a garden hose end fitting. It would only take a minute or two to put it on, fill up and then 30 seconds to pull it off. Just have the fitting and a screwdriver handy by the front seat when you pull in.
How do you by pass the check valve to allow water to flow in?
Same way when you use a standard hose at a regular tap. Might be a valve or valves you switch over.
I doubt they put in a fresh water tank and there is no way to fill it.
