Crappy Dometic toilets...need advise on auto filling

After all the problems I had trying to find the stench of the 300 why would I buy another dometic? I was desperate and it looked nice.(320)..dont stink yet n it works good if u prefill otherwise bad pressure and jet design....i think it has too many ports to get good flow...and never gets a jet around the front to flush the girls tp...

So I'm trying to mod this toilet after modding my wall to even fit this junk...it needs an auto fill mode, a tiny tank inline after valve to gravity fill a little or a delayed valve...or an accumulator right at the toilet? Anybody have and ideas?

I replaced my 300 after it filled up internal cavity with liquid nastiness. Went back in with a 320 with 'water saver'. Absolutely no problems with 320 after 6 years. Great flush, entire bowl rinsed well, no flush valve action problems, no issues with "residual water" afterwards being too low. But, I also run my water system at 60psi, and have better than a 4gpm flow at toilet. Shutoff valve was also replaced (same time as 300) with a full flow ball valve. I have no restriction between toilet and pump.

Push flush pedal half way down and add more water to bowl prior to using toilet

Maybe I just don’t understand the OP’s concern but we just make sure the seal is closed after flushing, then lift up on the foot pedal to put extra water in the toilet bowl. Black tank odors in the coach isn’t normally a problem as long as the seal is closed properly and additional water remains in the bowl.
