Sorry I did not respond as quickly as some members expected. One even suggesting I had long gone from the thread and members were wasting their time trying to help. One suggesting that the OP may have been a setup. Nothing could be more wrong. I have been away in my caravan for four weeks with scratchy internet at best and otherwise enjoying myself which is what these boards and caravaning is all about. As a rookie I appreciated all the help, but maybe not so much those posts trying to impart a little Shakespeare. Anyway I am here to advise the results of my weighbridge do-over. On returning from my trip I called into the same weighbridge and had a pleasant chat with the same operator. He was happy to redo the weights, at no charge, this time with the caravan unhitched. Both the TBM and GTM were less than the first time. This maybe because of less water and food on the returning trip but the TBM unhitched was actually 31kg less than the first time. The new numbers puts me under the compliance plate ATM, the printout I have filed away with my insurance papers. It has been a worthwhile exercise for me as I now know I have to lose some weight in the van when setting off and we are now deciding what gets left at home, starting with less water. Thanks again for all the help.
