What we have not checked
We can show you that 639554 is a real Thetford number, what Thetford calls it, and which parts lists carry it. We have not verified that it fits your camper. That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
