Almost collapsed my fresh water tank on my 378.
Today I refilled fresh tank. Coach was tipped quite a bit to drivers side. I overfilled the tank and turned it off when water began pouring out the overflow. Drive back to campsite (200 yards). Water continued to pour out overflow. I figured I had really filled it max.
Water continued. Looked at tank and saw that it had sucked in the sides of the tank! Only way to break the siphon was to get under coach and BLOW air up the overflow tube (getting very wet in the process). Then the tank sucked in air to regain normal size.
Thinking of trying to modify the overflow to provide a vent. Also perhaps to convert the overflow tube so I can gravity feed the fresh tank. There is no way currently to gravity feed tank. We have been using our fresh tank a lot this summer without access to hookups.
Anyone have any thoughts or experiences with this?
