Hi Mads!
You can use the Thetford Aqua-Magic Residence RV Toilet part # TH42SE, as a direct replacement for your Thetford 42176. It has the same overall dimensions and the same 9-1/2" rough-in, so it will fit well in the exact same spot as your old toilet without needing to move any plumbing.
This model is also a low-profile design, just like your original, and if you’d like to keep the hand-sprayer function, you can add the Thetford Hand Sprayer Kit, part # TH77UE, which is compatible with this toilet. Altogether, this will be the closest match to your old toilet in both fit and function, and it should install smoothly in place of your 42176.
