Water leaking from under stove, what is this unit

[Tony L]

So i stumbled upon a stream of water today in RV, Tracked it back to a unit under stove, What is this unit? Water doesn't seem to be coming from any of the hoses in the the front or the puppies that are aside but from directly underneath this unit?
What is this unit, and any inclination on to the problem

That’s your water heater. There are seals on the fittings, and if they fail or the fitting loosens, water will leak.

They are called “swivel seals”.

If there are no indications of a leak from any of the connections I have had one develop a leak from a tiny, tiny crack in a weld on the tank. I found a small pool of water that kept developing outside the wall inside the closet. Opened up the panel and checked every connection to no avail. Finally I bit the bullet and pulled the water heater (I was certain the leak was from it) and the water was coming from inside the styrofoam jacket on the tank. Replaced and all good.
