Strong urine smell in bathroom

Our new to us trailer on it's first voyage has a strong urine smell beginning in the bathroom and after pumping permeates the whole trailer. It's a dometic toilet. It appears to be tight and no seal leaks, I could find. I suspect it's a venting issue. Granted, it was 90 and we stayed hydrated so there is that. But black tank level was 1/3 full. We have not used any tank chemicals other than Galgon to this point.
help please.

Follow-up. We have used the camper this fall with daytime temps around 70 and night time in the upper 40's. No smell issues or other problems. It appears that at warm outdoor temps, the fan or other strategies must be employed for the bathroom to clear of smell because air will not vent through the stack efficiently enough to do the job. Aside from spray cover-ups, there will be a smell issue in the bathroom.
