Hi everybody, We have a 2007 Winnebago Alpine (predecessor of the Avida longreach Im told) we would like to replace the toilet as its cracked lid and stained. It is an Dometic VT2500 vacuum toilet. Could anyone tell me if the whole system would need replacing as the vacuum system still works okay so hoping to replace the bowl and lid etc. Thanks in advance! A starting point would be great!

Some vacuum toilet parts are difficult to get, especially the seals and pump. Check.
If you decide to replace it, I would suggest a composting toilet.
Cheers,
Peter

If you look on eBay parts quite often come up
We had one in our Alpine a really good toilet system
