LaMont, take a stick or rod (one you can get rid of when done). Turn your water off. Push down on the flush pedal and stick the rod down until it hits something. If you have an angle, you’ll hit that. If it’s an angle, use a hose as Carl suggested. If not and the toilet hasn’t been draining, you may need to change the valve. But the easiest first step is seeing if you have an angle. Our first Montana was a 3400, but I purged those files from my brain a long time ago. Best of luck. They make clear sections to connect on the sewer hose. Might be a good future investment.
