According to my multi-model Swift handbook, the Challenger 520 (note, not 520SE), the height including the aerial is2.76m (9' 1"). As the manufacturers seem to use the same box for several models, I would imagine, if there was a difference, it would be quite small. One can always measure it. Talking of caravan height, the first time we went into France via Le Havre, we arrived at something like 23.00hrs, in the dark. Not knowing Le Havre for obvious reasons, we were trundling along just outside the docks and overtaking a line of traffic when I found we were committed to going into the underpass. As we entered the tunnel at about 30mph, a sign flashed by reading "Height 2.8m". By this time, it was of academic interest as we were now in the underpass. There was a slight scraping noise as we were going through the trunnel, but on inspection the following morning in daylight, there did not appear to be any damage, although when we returned to the UK and I was washing the caravan, I noticed that the spike on the aerial was at a jaunty angle. When I measured the height to the tip of the aerial it was 2.810m. Phew!!! That was obviously what caused the scraping noise. Lesson:- When going towards the Pont du Normandie from the docks at Le Havre, keep well over to the right or their nearside lane and avoid the underpass at all costs!

If you are in need of finding the height of any object and are with out the means of measuring it
I have found if you walk away from the object approx twice the distance that you estimate as the height of the object to be measured Bend over with your legs spread slightly apart Look through your legs If you can not see the top of the object Move a little further away and do this procedure again Keep on with this method until you can just see the very top of the object to be measured Then divide the distance from the object to where you could see the top of the object by 3.25 and you will have the height of the object + or – 10 %

The basic principle is there My maths may need a little bit of work
The Romans or was it the Greeks were the first to work this out It is all to do with triangles If you can work out the length of one side of a triangle and the angle of one other side then you can work out the third angle and distance
Just depends how long your legs are

Most people think that Pythagoras was a Greek. Oh no! In fact he was a North American Red Indian. He had three wives. One slept on a buffalo hide, one slept on a horse hide and the third, his favourite, slept on a very expensive, imported hippopotamus hide. In the fullness of time, they each bore him sons. The wife who slept on the buffalo hide bore him one son and the wife who slept on the horse hide bore him one son. The wife who slept on the hippopotamus hide bore him two sons. Thus proving his theorem that the squaw on the hippopotamus is equal to the sum of the squaws on the other two hides
