Just picked up a 2006 Attitude 26' toy hauler 2 weeks ago.....
It has two 50 gallon water tanks.
We went out w last weekend and had a little problem.

we ran out of water a little to quick....
I crawled under the tanks..... first tank was empty and the 2nd tank was full but not transferring to the first one. maybe a vent type problem. It was saturday night and I just poured in 30 gallons from a drum I had in the bed of my truck into the 1st tank.... all worked well.

Today I emptied both tanks at home.....

2nd tank 1.5" transfer hose was 100% clear and also the 3/8 or 1/2" vent hose.

Soon why didn't the 2nd tank transfer over to the 1st tank last weekend?

Thank you for your help folks, Robert.

Hopefully it was a one time fluke.
I was helping a friend with a similar issue years ago and it drove us nuts to figure out:
One of his tanks had a thick paper tag floating around inside of it. The tag would get pulled into the drain/cross over outlet and stop the flow. We dropped the tank to fish it out. Took a few weekends to figure out something had to be in the tank..........
