Towing vehicle for two horses – petrol or diesel?

Hello, I’m looking for a towing vehicle that can pull 2 horses; with two rather large warm flowers at least 2 tons of trailer load have to be used. The car should usually be used as a normal car, does not cost more than 15,000 EUR, is moderate in maintenance and does not let me stab on the first muddy meadow – the egg-legging wool milk sow just ;-). After rough overturning of the weights (Hänger approx. 800-1000 kg, 2 horses approx. 1200-1300 kg) come own After my research only the following off-road vehicles in question: – Kia Sorento – Nissan X-Trail – Hyundai Santa Fé – Landrover Freelander All the other off-road vehicles I know, which are allowed to pull so much, are simply too expensive or have already run a lot as used ones. At the moment, the Santa Fé seems to me to be the most suitable one, since it is also brought quite well to get. Should one necessarily buy a diesel or also a petrol truck withstand the towing load? Is such a search only question the following off-road vehicles in question: – Kia Sorento – Nissan X-Trail – Hyundai Santa Fé – Landrover Freelander heavy car as a diesel (exception: X-Trail, who won all possible tests as a diesel) not too cumbersome in everyday life? I drive about 10,000 km a year, maximum 15,000. What do you think? Thank you very much!
