Zeus,
I always like your posts. Your unpretentious and honest.
I'll be the same with you.
WFP is a pain in the winter, unless you have a garage or a shed; somewhere where you can get your gear out of the freezing cold, so it's not all frozen up in the morning; a heater helps.
But, I usually dump all mine in the kitchen (much to the annoyance of Wor Lass); RO unit, poles and backpack.
Water barrels don't usually freeze; maybe only a little bit; so I put these into the car the evening before work.
Keep your gear out of the wind.
I remember leaving my brush out all night, and the first job in the morning, I touched it against a window and felt a 'thud'.
It was like putting a solid block of ice against a bit of glass.
Winter is a pain with WFP.
