Lutz: I agree that it is cheaper to use a weighbridge when required but it is not always very convenient, to my astonishment, my local caravan dealer couldn't tell me where to find the nearest one. We spend a lot of time in France and as a consequence we we take a lot of kit with us. Also it could be quite difficult to find a weighbridge in the middle of France should we need one. I have a suspicion that many people ignore this subject, they just load up and hope for the best; people have even asked what I'm doing when I'm measuring the noseweight!
