Usually when this happens, the whole handle and rod come out.

This is also my guess from a distance. We've had several reports of black tank flush not allowing any water through the vacuum break.

Took the drain hose off this morning. Looked down with a flashlight. Assuming the valve is silver it is not opening. Looks the same down there whether the lever is pulled open or pushed in to close. Gray doesn't drain either. I've been assured nothing but the Scott RV toilet paper we bought was flushed down. And we have had no problem with that for the last few weeks.

It sounds like the gate valve to the tank is not opening but it does seem odd that BOTH the black and grey would quit working at the same time. Especially, since you mentioned you emptied them yesterday during the first go round with no problem.

Run some water in the sink/shower with the grey valve open and see if water comes out the sewer port?

You said you seen something silver inside the sewer pipe. Most gate valve blades I've seen are black or white/translucent. Maybe there are metal bladed valves but I've not seen any?

If you get no water from either the grey side (or the black side) and you feel confidant the valves are connected to the pull handle/cable and working, I'd guess there is some kind of blockage in the pipe. A snake may be the only option.

I'd start with only the grey valve open when snaking.

I have a 2015 Wildcat 327ck fiver and there is a tag near the black tank flush and it states not to close the blank tank valve when using the black tank flush. Is that the case with the Flagstaffs?

And this from a guy that made a BIG point in Goshen that HE NEVER DID #2 in his camper toilet. Ms. Amy said she did and he would empty it whether he liked it or not!

SO, do you or do you not do #2 in your camper toilet????

That's the case with any RV with a black tank flush. It's because it's easy to turn it on, get distracted with something else and then have a huge mess to clean up in the bathroom because the tank overflowed.

Black tank clog

Agree that the drain line after the valves is probably clogged. You can do a snake but be prepared to have someone shut off any open valves or you will have a real mess. You could also try to use a clear adapter with the flush connection and reverse flush the line, this may free up the clog. If you determine that it is a clog, I Would ultimately do the following get a clear adapter with the flush connection, unscrew the flush connector and run the snake up thru the opening this way you can leave the tanks open, to have that pressure help move the clog, once the clog lets loose put a rag over the connector hole and let the tanks empty.

To prevent this in the future make sure you keep several gallons of water in the black tank. This will prevent what is called the dreaded mound. This is when all the material that is flushed drops straight down the toilet and forms a mound of hard material. Keeping water in the tank lets the material move away from the bottom of the toilet.

Please let us know how you make out. Good luck.
