Question:
Im replacing a Thetford Aqua magic 2 with a Dometic 320. Will this be a direct replacement? Do you offer a tall oval option?

Expert Reply:
Hey Robert, the Dometic 320 part # DOM27FR could possibly be a direct replacement for your Thetford Aqua-Magic Style II RV Toilet # TH35SE but it comes down to the dimension from the mounting bolts of your toilet to the back wall behind it. If it's 11 inches it will easily fit but the toilet you have now has a 9-1/2 inch minimum dimension so it's possible you only have 9-1/2 inches which would not be enough. If you have 9-1/2 inches or something different let me know and I'll see what options we might have.

Everything worked out perfectly. Fit perfectly in my 2019 Grand Design Momentum 21g. Highly recommended.
