Posted by Tim Parremore on 22nd Nov 2023

In the world of off-road adventures and caravan towing, upgrading your vehicle's Gross Vehicle Mass (GVM) is a well-known practice. However, what many enthusiasts might not be aware of is the equally crucial upgrade: Gross Combination Mass (GCM). In this blog, we'll explore the critical distinction between GVM and GCM upgrades and shed light on why over 95% of the time, both are essential when towing a caravan. Moreover, we'll unveil how, in the picturesque landscapes of Tasmania, achieving GCM increases is not only necessary but made possible with the cutting-edge Lovells suspension kits available at TJP Auto & 4x4.
