Looking for toilet upgrade advice...

We installed a Dometic in our Airstream and it was a very nice improvement. Not all of them (Dometics) have the same measurements. Take a look and you will see the differences. Make sure you measure your existing space to see that a new one will fit there.

Mine required that I make some modifications to the back of the lid and I ended up having to do some plumbing to get it connected. It was all rather easy and we are happy with the results.
