Well, I'm happily embarrassed to say that it seems the problem was just the external water line connections needing tightening... Is taking it out as easy as undoing the waterline and the two bolts on the floor?
Good on you for finding it without major surgery! Let me mention, this isn't the first time this has happened.
Please install a shutoff valve in that supply line while your mind's in the toilet. Here's one that just pushes in place, a "Sharkbite" design. I think it'll have instructions how much of the tubing to cut out. So long as you have enough straight run, it's very easy.
In Amazon, "plastic pex valve"
A house, of course, has a shutoff at every toilet, every faucet, most appliances (dishwasher, clothes washer, icemaker). Impractical to do that in an RV, BUT... The Toilet is probably going to be the one that would otherwise force you to turn the whole water system off. Shower or faucet may drip, but that water goes down a drain.
You made a very good find. I ended up repairing our floor around the toilet. I think prev owners had a leak where you did, and tightened those two flange bolts thinking that was the problem. So my repair included a new flange.
