Has anyone had experience in replacing the shut-off or would the whole tank need replacing? What would be involved?
I have done this on an older AS - a 66 Caravel
. Really - I only took it apart and cleaned it. You may find the gaskets have rotted or may be as simple as TP clogging the grove where the slide valve goes into. A cleaning may get you back on the road but for your late model valve body there are repair kits available from most RV stores and from an AS dealer. That would be a start and as Andy says above - it's not to hard but I would not have "cake" in my answer to you - seems a little out of place in a discussion over a dump valve.
