Trailers are often known for the use of AAV's which is a one way device that protects the trap seal. I would suspect that you have a blockage that is causing the drain to pressurize when the toilet flushes. I would call a pro to diagnose the problem and clean the affected line. No chemical drain openers please... Save your money for the repair that works!
