Filling a hidden fresh water tank
On the past RV's I've filled there's a separate tank filler and city water hookups. On our current Jayco it's all in one just change a few valves and open one of the faucets. The problem is when is it...

When you say it is "hidden", does that mean you can't access it at all, or that it's just not visible from the filler? On my motorhome, the tank is located in the same compartment where the water pump is, on the side opposite the filler. The low-point drains are also in the compartment. When I fill the tank, I always open the water pump compartment and watch the tank level while it's filling. Incidentally, mine does have an overflow tube.
