Mine is a 2.4Litre turbo intercooled diesel with a 3.1 tonne tow capacity, I tow our 23' yacht, about 2.5t, two horses in an extended float also about 2.5t, it does this through the hills without complaint, my only beef is the yacht that has overide brakes that thump in, the float has electric brakes but they are no good on a trailer that is used to launch and I am not about to fit hydraulics.
I bought this for the comfort factor too, all leather, climate control, auto lights, high beam, wipers, collision avoidance, lane departure etc etc etc, I'm getting older and lazy.
A tonne (1000kg) and a ton are so close it is barely worth converting
