Question:
Can you recommend a replacement with the 8.5” minimum from wall. I have no extra room and rear wall cannot be moved. Has the design flaw been improved on the 300? Is there an adapter flange to move new toilet away from rear wall? Thanks

Expert Reply:
The only RV toilet that we have available that will fit your 8.5" rough-in measurement is the Dometic 300 Weekender RV Toilet.
- Dometic 300 Weekender RV Toilet # DOM64FR for white
- Dometic 300 Weekender RV Toilet # DOM74FR for tan
If the flaw on the 300 series you are referencing is the faulty seal/design that allowed for waste to collect and cause odors, then the answer is yes it has been fixed. Per Dometic the issue was addressed and corrected in manufacturing.
There is not currently an adapter that will allow you to use a RV toilet with a larger rough-in distance.
