Towing your pride and joy?

Yup, I learnt this the hard way, I used to tow large refrigerated display trailers to markets etc using vans. often the vans were well loaded with stock as well. To try and keep the weight distributed we used to try and not have too much weight on the nose of the trailer - big mistake - you couldnt go much over 25 mph!!
On one occasion I had a wheel bearing go on a trailer and they recovered it on a car trailer, however because of the length of it the rear of our trailer was hanging over the back, plus this was where the fridge motor was, I was following the guy who was towing using a big double cab Navarro - all of a sudden there was a little wiggle and then within a few seconds the back of the trailer was in the hedge and the front of the Nissan was in the opposite ditch, very nasty.
