On our vehicle's V5 the Technical Permissible maximum towable mass of the trailer is 1500 braked (line 4 o1). So does this mean as beginners we take 85% of this and this is the MTPLM of the caravan?
Definitely not!!! This figure is, I believe, the mass of the heaviest trailer that the towcar is structurally adequate to tow and that it can restart on a 12% gradient. It has nothing to do with safety.
The 85% guideline recommended by the Caravan Club and others for a reasonably safe outfit refers to the actual mass of the caravan as towed (i.e. the MIRO plus the junk you fill it with when you go on holiday) and the kerbweight of the towcar.
