Fresh Water Tank Location

My DH and I recently picked up our new Zinger ZT26BL.  I've figured out where to fill the hot water tank, it's location, where the low point drains are, and (I think) where to fill the fresh water tank.  But I have no idea where the fresh water tank is hiding!  May be a stupid question, but I am used to being able to monitor the fill level by looking at the tank (then again our old trailer camper was 17 years old when we sold it last year so things have changed a bit).  Where would this massive 54 gal. tank be located, and is there a way to monitor how close it is to full without using the light-up panal?

Thanks!  The underside of our camper is covered, so I'm assuming that is where it's been hidden.  The old camper had it under the master bed...which is all storage in my new Zinger.  It's amazing how much things have changed over the seventeen years since my parents bought the old one, and we bought our new one!  Now, the weather just needs to warm up and stay that way so we can take it out!

 CR usually has the fresh water tank way in the rear, on all that I've seen. If your filler is back there, look underneath and you should see a plastic tube with a cap on it sticking thru the membrane, that's the drain for the tank.

The tank could be mounted anywere(front middle back) like Farmer said look for the small drain hose sticking out with a threaded cap on.
