Been around the RV hot water heaters since 2004 and have yet run into one that was leaking due to the main body of the hot water heater. I have had leaks with the high pressure valve and a hot water external hose one time.
I have removed the bottom port for draining water and inspections a few times.
Just curious where your leak is at - perhaps associated with a winter freeze-up or something like that...
