Is there a definitive guide for dewinterising a 2022 320?

CCC

Sorry if this a repeat. I find that the search here is not very good.

I do not think there is a specific guide for the 320 or the 400.  However, this is part of my list

check the air in the tires, including the spare.
grease the bearings

check and charge the battery, check solar charging.

flush the water system of anything, I air dry mine and do not use anti freeze so flushing with new water is my first step.  Then I drain everything and refill with city water and leave for a few hours to sanitize. Then drain and refill if I am going out.

check all water fittings to make sure they are tight

Flush the toilet

hook up the propane and test both the stove and Aldi to make sure they fire.

open and close all windows and run the fans.

drain the gray and black tanks.

test all electrical on battery and plugged in to power.

make sure the frig cools.

adjust brakes as necessary.

Check TV and audio system operation if you have them.

clean and vacuum.

…… and I am sure there are other things to do.

If you don't know exactly where your drain valves are, you might ask for a bit of help.  But, this thread:
