Boss Adventure Sorrento 18 - Two Bunks

Always check your compliance plate
Online databases use factory-standard specs. They do not know about the bullbar on your car, a suspension upgrade, or how much you are carrying. Each one changes your real limits.
How to find it
Open your passenger or driver door. Look for a silver or black metal plate riveted to the pillar. This plate overrides everything you read online.
Why the numbers move once you load up
The figure most often left out of the sum is payload, which is everything you add after the vehicles leave the factory.
- • Bullbar and winch: both add weight to the front of the car, and it comes out of your payload.
- • Passengers: everyone in the car, including the driver, comes out of its payload.
- • Ball weight: the weight the van puts on the towball comes out of your car's payload as well as its towing limit.
Work out what this van is allowed to carry, then check the figures before you pack it.
Always weigh your rig fully loaded.
This pairing is inside the published ratings, with not much room left.
Gear for a van close to your limits
The published weights sit close together here. A weight distribution hitch moves some of the towball load onto the car's front axle, which is where the ball weight takes it from.
