What do you do to winterise your MH?
All I can think of is making sure the fresh water and waste is empty, put in a small electric heater and run a dehumidifier at least once a week.
Anything else worth considering?

I"d say draining and leaving the taps open should suffice and try to use a plunger to empty the u-bends in sink drains.
