Why not look their locations up in your owner’s manual?
This is always a great reply, but unfortunately, for many of us the "owners manual" is a super generic collection of information that generally doesn't apply to any specific model in the line. It's included so the manufacturer can say they included an owners manual.
That said, there's some manufacturers that document their specific models. I helped a friend once on his MiniWinne, and it was a precise document of the unit.
Our low point drains on our 2016 2250 Sunseeker are in two locations, the FW tank drain is indeed below/beside the FW tank (valve on the blue line at the left; tube emerges below the MH):
But the line drains are below the kitchen sink just aft of the side door:
