The weird thing is, that we mostly emptied our black tank before leaving to come home from each trip, and only leave just enough water in the bowl to cover the seal and a very little in the black tank for the water treatment pod between camping trips.
What kind of toilet? If it is a Dometic 300, there is a known problem. They made the bowl in two pieces and water gets between them. Dometic will send you a complete 310 for a small fee if that's the problem.
Since you mention that it happens on the way home, but not outbound, think about this:
On the way outbound the water system is not pressurized.
On the way home, the water system is pressurized; either you were running the pump or hooked up to "city water" before you pulled out. There are check valves on both sides that prevent water from "going backwards", so you still have pressure. Now, as you ride along and the trailer bounces, the line flexes and a little water squirts out. So pressurize the system and reach behind the toilet and wiggle the line around gently. You may find a joint that's not quite tight enough, or that the valve is not fully inserted into the toilet, or even a tiny crack in the line or valve. (The toilet valves are known for cracking in freezing weather if they are not fully winterized.)
Be sure to let us know what you find.
