Roof Problem: does it leak, or does it not leak??

Here's a question for you guys. The previous owner of my 79 Dodge Tioga said there was a slight leak in the roof over the the overcab bed. I can see where there was slight damage from the leak but nothing major. He resealed the roof with EPOM just a few months before I bought it. The resealed job looks good. The roof looks nice and is in good condition.
Since I have owned the RV it has survived many intense rain storms. I check the trouble spot for leakage after each storm, but much to my surprise there is no signs of leakage. Being that a former RV I owned had a very leaky roof until I repaired it and it was obvious. Maybe the EPOM sealed the crack where it was leaking?? So far I have had no problems with the roof and we have had some scary weather. So I am puzzled. Any thoughts??

Don't know what an EPOM sealing product is, EPOM seems to be an internet ad service. Now an EDPM (ethylene propylene diene monomer) is a synthetic rubber sheet material that is commonly used for flat roofs and RVs. It's a very durable roofing material with yearly checks for caulking cracks around edges and vents.

If the roof was properly coated and sealed with self leveling caulk, it very well could have been properly repaired. Go on the roof and check joints and all piercings from skylights, vents, A/C units, etc. Dicor self-leveling caulk is a good product to use for repairs, it can be applied over old, cracked seams. Do not use silicone caulk, it fails and nothing will stick to where it's been used.

EPDM is correct. My mistake. Yes I believe it is a rubber roof.

Got yeh. I will look over the cab bed, but I don't see any trouble spots, and again it doesn't seem to leak. So perhaps this is a good thing. Just need to take it to the car wash, because of all this dirty rain. LOL. 🙀

Update: I have determined there is no longer a leak in the roof. I checked it during extreme rain down fall. I believe the last owner did indeed fix it when he resealed the roof.
