That is a skill that has always fascinated me. For a short time we had a tourer and I was hopeless at reversing into any given plot.It is a long time since I towed a caravan but motor movers had not been invented. We just reversed onto the pitch using the car. Mind you I was used to reversing farm trailers and when artic lorries first appeared I often had to reverse them into our loading bay as the drivers had never been trained and could not cope with tight spaces. This was on private land so no insurance issues regarding road traffic laws.
