Yes, they trip or blow depending on if the device is a resettable breaker or just a fuse. As you suggest, put the blacklead of your VOM on the battery negative or the RV frame and the red lead on the suspect breaker first on the post with the battery attached which should read about 12VDC, then move the red lead to the other breaker post. If it reads 12VDC then the breaker is OK, if not it has tripped. At this point you need to remove the battery power so you can examine the breaker safely. If it is resettable, there should be some sort of reset button ow whatever. Very often, these breakers are undersized, so if this is a 30A breaker get a 50 if a 50 get an 80 and so on. Things like battery health, and temperature will change the amount of current the motor will draw. If you only have the dealer installed battery there is a reasonable chance it is toast. You might want to look into getting a pair of Trojan T105's if you are doing more than weekend camping. Key point is NEVER letting the batteries drop below 50%, get a Bogart Trimetric TM-2030-RV or similar as long as it uses a shunt.
