How many are aware that some vans can have their MPTLM increased simply by asking the manufacturer to issue a new tally with the new MPTLM and tyre pressures and a certificate. Not all vans can be done but my Bailey Series 5 Pageant Bordeaux has gone from 1366kg to 1400 kg. All Bailey required was a £50 administration fee. It now means that my new mover and 110amphour battery do not reduce my normal touring load.
