zippybiker - how to fill FW tank on 5th Wheel

[zippybiker]

My friend has a 2005 Jayco Designer 5th wheel 37 feet long. We cannot figure out how to fill the fresh water tank, or where the tank is located. Any help will be appreciated.

Look underneath. We camp with some people with a jayco around then and the gravity full is underneath. Right off the tank.

I have a 2004 Designer 5er, and the fresh water fill is a screw cap on the rear, right beside the city water connection. Tank is under the rear of the trailer. Look under the trailer for two short hoses sticking down - these will be the overflow hoses for your FW tank. Nearby should be a valve to drain the FW tank.
