Question

I need a new holding tank for my Stirling Eccles Opal 2008. CWE200 Thetford Toilet. dark Grey with wheels. Can't seem to find a replacement on your site.

Answer

If your tank is dark grey with wheels then I think you have a C250 toilet as this is the only one where the holding tank has wheels. To be sure there will be a data plate inside the area where the holding tank sits which will confirm which toilet you actually have. If you do have a C250 then you need our part number 137463 which is a completely new holding tank.
