We just replaced our Thetford AquaMagic with a Dometic 311. We'll see how happy we are with the replacement.
While looking at what would fit in our trailer, I found that there are Thetford AquaMagic replacements which would fit and you might consider those.
Why did we go with the Dometic? A YouTube video showed internal cavities in the Thetford products which can trap waste matter during flushing. Sure enough, our old AquaMagic had those. Does the dometic have the same thing? Perhaps, but we will see.
