the best advice for towing in Britain is to stay at home , we had over 500 miles of towing through snow in France last December it was a nightmare , but at least the French keep the motorway moving , while britain came to a standstill , the front of the van had snow 4 inches thick chucked up by the car wheels ,the hitch was full of snow and the wheel arches were caked full and the roof was covered god knows what the van weighed , the wipers were getting clogged in ice even with the heating going full blast on the screen ,so at every service area we got a broom out and cleared as much as could off ,and banged the wipers against the screen to clear the ice , we were going to pull off and find a site ,but i am glad we didnt , because we spoke to caravanners who came in a week after us who did pull off , and they said once they got off the motorway they got stuck because the side roads had been cleared , but as we came near to Montpellier the snow cleared , but even approaching Barcelona at 8,am we had temperatures of minus 8 F , but at the moment i am in sunshine in Australia , and what a lovely lifestyle it is here , but if you do go in the snow take water with you for hot drinks , and make sure you have plenty of propane gas , also a shovel and broom ,warm clothing , keep the car in 4 wheel drive if you have it ,anti freeze screen cleaner , we were lucky we had a small ladder in the van ,because we awoke one morning in the services and a lorry had parked so close we couldnt open the caravan door ,so i had to lower the ladder out of the window and climbe out and then pull forward to let my wife out , ,any wat thats our experience of it
