I have a 2021 Freedom Elite and couldn't find my hot water low point drain valve, neither could anyone else. I registered my FE with Thor at https://www.thormotorcoach.com/owner-resource/
and all the manuals for everything in your particular RV are there in PDF form. I found the manual for the HW tank and found out there is NO low point drain. It says to drain the tank by removing the tank plug, open the HW tank door on the side of the RV and you will see it. It also says there will be approximately 2 quarts of water remaining in the tank that won't hurt it if it freezes. To blow out those 2 quarts it has to be done through the blow off valve. So I guess the old saying still holds true; when all else fails read the directions!
My potable water drain is under the bench seat closest to the cab and the HW tank diverter valves are behind a panel under the kitchen sink. Good Luck!
