Depending on the make and model of the RV Refrigerator you have, it could very well have a drain on it. That drain hose could also be plugged up causing the problem you are experiencing.
I cannot tell you exactly where to look for the drain hose as the location will vary by the model fridge you have and how the RV Manufacturer ran the drain hose when they installed the refrigerator in your RV.
If your RV's Refrigerator is equipped with an Ice Maker there could also be a leak in the water supply hose attached to the ice maker that could also cause the problem you are experiencing.
Unfortunately you did not provide me enough information on your fridge or problem for me to even make an educated guess as to what is going on.
I suggest that you take your RV in and have a Certified RV Technician take a look at it. Even if it is something as simple as a plugged drain hose, it could require removing the fridge from its cabinet to access the plugged hose or leaking Ice Maker supply hose.
Also depending on how the manufacturer installed the fridge in your RV it could require complete disassembly of the cabinet that the Refrigerator is in.
Sorry that I could not be of more help.
