Re: Fresh water tank filling,

Yes, you seem to have it correct, fill and have onboard water. We tend to fill our tank and then use the 12 volt pump for our needs. Only when we are staying a while will be use park water and then I will leave the grey tank valve open as well.
You can watch the tank gauge as it fills, and you should be able to hear the water splashing into the tank.
My old overflow green, painted black, plastic hose was brittle and broke off, be very careful. The screen over the end keeps things from crawling into the tank. I also made sure the overflow hose did not run water down the coach wall, it spills onto the ground, missing the coach parts.
Your photo of the vacuum tank shows the metal pressure switch. Not sure why you have oil on the wall. I replaced my vacuum pump when I realized it did not shut off, and sounded like someone beating a hammer on a anvil. We tested the switch, and the tank, both worked. The pump was running all the time to maintain the dash vacuum for the blend doors of the dash heating and cooling system.
