I have just joined the Forest River Forums so I hope I am posting this properly
We just bought a 2021 East to West Alta 2600 KRB and have just completed one week of camping in it. We are happy with it, it is quite an upgrade from our last trailer.
One issue we had, was after filling up the fresh water tank, the 2 overflow hoses kept running and were draining the fresh water tank - it was like they were siphoning the water out of the tank. There are 3 hoses running out of the fresh water tank - one is the tank drain hose with a shut-off valve, and the other 2 hoses do not have valves.
I have a call in to the dealer to inquire about this but was just wondering if anyone else has had this problem.
