Purchase advice off-road vehicles

Hello, My father has long been looking for a good off-roader / ofroader, his problem is that he has many requirements or limitations… 1. Attachment load min. 2.5t ! 2. All-wheel drive 3. Lock differential, because we live on a very steep slope with private road, which is not always well passable, because only the neighboring farmer cleared. 4. Consumption of max. 12L (best by 10 or even less) 5.Price max. 1200 net (if VAT can be declared) 6. Good would be automatic since he would be a The purpose of the car is to pull heavy trailers (horses trailer up to 2,5t, big trailer up to 2,7t which he takes for wood transport) which is why the car should be able to pull the 2.8t best. In addition, he lives in a house with private road which is as already mentioned very steep and he wants to be able to drive all year round also with trailers with high weight. (currently VW T 5 o) He thinks Japanese off-road vehicles are quite good, so far he has: Nissan Terrano 2 2.7 TD Mitsubishi Pajero Nissan Patrol Jeep Cerokee Nissan Pathfinder Toyota Land Cruiser So I think the most important thing has been said… I hope you know something about this MFG Felix
