Importance of a Vehicle GVM Upgrade
A GVM upgrade allows more scope for accessories like bull bars, long range tanks, roof racks etc but still has its limitations, especially when towing. If towing you will often see the most benefit from a GVM upgrade when towing a lighter weight Caravan or Camper that is well under the Brake Towing Capacity.
This mean you have plenty of additional weight to play with before nearing the critical towing weight restrictions. As well as GVM, it is important to understand the effects of GCM (Gross Combination Mass), Axle Capacities, Ball Weights and Brake Towing Capacity.
Most importantly, exceeding a vehicles approved GVM could lead to a costly fine, void your insurance and make your vehicle unsafe.
