Re " I tried using the pressure relief valve to help drain the water heater. It failed and wouldn't hold pressure after 2 times They are not meant to be used like that."
A common practice in Alaska - but owners close/re-seat the valve when water stops draining... 'Have not experienced leakage when repressuring tank in late spring/early summer, with proper air pocket.
Re "Leave the coach plugged in and the battery charger on...
Few Alaska aircraft and RV/boat storage locations provide 120/240 VAC. Owners of that equipment manage wet cell (and AGM) batteries as described.
Re "I wouldn't mess with the genset, I doubt there's any fuel in the carb unless you have used it recently". 'Necessary action in that climate as rate of vaporization is very low late August - early May. 'Heavy ends of fuel tend to form "gum" in carb bowl and around needle valve and has to be dissolved with alcohol before re-start. 'Experienced that in first year of long winter storage in Alaska...('should have listened to the "sourdoughs" as they advised me to do that...)
'Necessary to clear snow from flat roof RV equipment as snow load occasionally approaches 40lbs/sq. ft. ('design requirement for residential construction at 62N Latitude). Although the usual snowfall is about 7 ft., at about 9 1/2 ft. the design load limit is reached, depending on moisture content of the snow. There is usually little thawing from late Oct.-mid April at that latitude. As I didn't know the snow load design, I cleared snow on my Coachmen RV at about 3'. 'Not necessary on GMCMh and Airstream...
I cite this Alaska experience at there are L48 locations that have winter conditions similar to 62N. Latitude but usually for a much shorter duration. So, if it helps...

I tried using the pressure relief valve to help drain the water heater. It failed and wouldn't hold pressure after 2 times They are not meant to be used like that.
Not fun to replace.
I drain everything, I pull the anode out of the water heater to drain it ( make sure you depressurize the system first! ) Pump the pink crap through everything and dump it into the drains.
Leave the coach plugged in and the battery charger on.
Also check the antifreeze
I wouldn't mess with the genset, I doubt there's any fuel in the carb unless you have used it recently
But I live in Minnesota and -20 is not uncommon, it's has to be done right
