There is a leak under our sink I suspect it's the water heater but don't know for sure, I've dried it up as best I can with wet vac and blower, drained the hot water tank and switched to the water pump, any tips on how to know for sure and how long it will take, if it is the water heater is the only solution replacement? Thanks

Need to get to the back of the water heater to examen. When the water first appears, is ithot? It could be just a fitting.

Can the back be accessed by taking the outside panel off? Thanks
 
It is accessed often behind a panel on the inside (maybe under the sink or nearby) on the inside of the coach, or from an adjacent storage compartment, on the outside.
 
We had the same issue with our Leprechaun and it turned out to the fittings to the WH, just tightened them up and no more leak.
