I would endorse the don't do it as age and prudence take over
When I worked in Berlin in the 60s I learnt the hard way about towing in the snow
I was asked to collect a caravan from Hamlin by a friend
We set off down the 110 mile "corridor" through East Germany and the autobahn was covered with deep snow but then people didn't let that stop them as snow was present several months of the year
The British Government didn't recognise East Germany so we were as military employees forbidden to stop on that autobahn or have contact with East German authorities
We did break the rule and stopped to inform a traffic policeman that a car had gone off the road
It appeared in my rear view mirror but not the offside one rather the nearside one as an overtaking manoever resulted in it going off the road backwards
We stopped and tried to fit snow chains but the car slid on the ice and in our ineptitude came off the VW jack and this was before we collected the caravan
We did get back to Berlin safely if not a little stressed
Poor old Brian who I took to collect his van was a nervous wreck
Its not surprising as his previous autobahn trip had resulted in him upside down hanging from the seat belt after a rear end collision
It really was the cold war that day in more ways than one
Its hard to believe that Berlin was isolated and how diplomatic relations were or how much paperwork and security was involved to go out of the city
But enough digression
Avoid towing in the snow if you can
Its snowing now!!
