Why not do whatever is easiest for you?
We just dump and close the gate. No trap. The septic hose can be left in place and used for periodic flushes. No big stink unless the toilet gate and the tank gate are open to the septic system at the same time.
A trap that would not freeze can be above ground, fabricate it out of the same materials as your septic line. our line was too high in the ground to put a trap underground, not worth the money.
