We keep our caravan on our drive. To reverse it on with the car is a major struggle, due to a combination of the narrownes of the gate, the angle of the turn and that we live on a T junction. Also rubbish at reversing but it would be really tricky anyway. Usually unhitch and powermove it. Any hoo, we have enough length to drive on so that the van is off the road, unhitch, move the car to the side of it and then push the van to the top of the drive. The drive is basically a triangle with the apex at the gate so it is not the same length all the way down. Trouble is the van is then pointing the wrong way to tow it off again. How wide does the drive need to be to turn the van through 360 degrees? And how much length of that width will we need given that the drive is triangular? It is a Swift challenger 490 length 7.18m width 2.29m. Hope I have put this clearly enough. Any help gratefully recieved, no idea how to work it out!
