I have a 2006 fleetwood wilderness with a fresh water tank under the frame with welded support bars that you can not remove on each side of the tank so my guess is they installed the tank from the top before they put carpet and queen bed in the room. Does anyone know how to get to the tank so I can install a new hose. I could not get to it from the bottom there is not enough room to get my hands in there. Thanks for any information you may provide.
