Without knowing your normal dumping procedure, I would suspect a poop pyramid. You might want to try one of these.
On edit: If the toilet burps on every flush, even after dumping, the other possibility is that the vent pipe extends too far into the tank.
30 years of RV'ing and I've never heard my toilet or anyone's for that matter burp!!
Yet you read on the forum just about everyday that people have 'toilets that burp all the time' and some 'know when to dump' when it burps? :?
Perhaps you are right that these RV's that 'burp' have a pipe installed wrong! I'd find it real difficult to believe that these manufactures make RV toilet systems that burp!! :B
