Can a Mercedes-Benz G-Class tow
a Blue Sky Caravans Ruby II / Back Door?
G300 CDI Professional (2010), checked against the manufacturer's published figures.
Close to the limits
The Blue Sky Caravans Ruby II / Back Door's published ATM of 2,685kg sits 455kg under the Mercedes-Benz G-Class's 3,140kg braked towing rating.
At a ball weight of 10% of ATM, which is an estimate rather than a published figure, the Blue Sky Caravans Ruby II / Back Door would sit above the Mercedes-Benz G-Class's 140kg towball rating. Ask the manufacturer for the published ball weight.

Always check your compliance plate
Online databases use factory-standard specs. They don't know about your bullbar (adds weight), suspension upgrades (can change GCM), or how much you're carrying.
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 comes out of its payload, not just the driver.
- • Tow ball mass: this comes out of your car's payload, not just your towing limit.
Always weigh your rig fully loaded.
This pairing is inside the published ratings, with not much room left.
Improve your stability
The published weights sit close together here. A weight distribution hitch spreads some of the towball load onto the car's front axle, which is what the ball weight takes off it.

Every figure here describes the two vehicles as they left the factory. Yours has a history since then, and the plates on it are what that history gets measured against.
