What a mess, although the cab still looks ok, but lucky escape for the passengers.
One report says the RAC were on route to the breakdown with a specialist recovery lorry, it doesn't mention them being left stranded by the RAC. So more facts are needed before any judgement of the RAC. If it turns out they were indeed visited by a recovery vehicle, who then left them, the RAC need taking to task.
The occupants should have been well up the bank, dogs left in the back of van. That where us with MH are lucky, we would almost certainly have warm clothes blankets etc, with us.
