I have a 2008 Fleetwood Discovery 40X. It is supposed to have a 50 gallon gray water tank. I can only put 32 gallons in. Called Fleetwood and they were basically useless. Any ideas?
I can tell it is full by gauge and water backing up in shower. I am the second owner. I will contact the original owner and ask him about it. Fleetwood said it was originally built with a 50 gallon tank. Thanks everyone for your help. I will post what I find out.
