Question:

Does the Dometic 410 have the water hookup at the same place as the 310? Wondering if I will have to adjust plumbing

Thanks for reaching out George, happy to help!

The Dometic 410 series toilets # dmc44jf are designed as replacements for the 310 series models and use the same general rear water supply connection. While the exact valve position can vary slightly due to differences in the toilet base design, you can typically reuse the existing water line, especially if it's a flexible supply hose.

Dometic 310/311 models to the 410/411 models, Dometic kept the same rear mounted 1/2" NPT water connection but the toilet base molding and shroud are different.

What style of RV/Motorhome are you making these changes to?
