Looking for off-roaders with reduction gears?

hello the round, I am looking for a second car with a used off-road vehicle with a lower gear. I need the car mainly to drive up the mountain. at the moment I drive a toyota rav4 (BJ 1995) – and was so happy up to now. unfortunately, the coupling is due (because of the lack of a lower gear) and apparently this should be extremely expensive to change (especially if you can’t do it yourself :-() therefore my question to the experts: which brands (models) h aben because still a lower gear so that I can make myself looking 🙂 size and age are second-ranking at the moment – important is a good condition, little rust and it should not exceed my budget of max. € 4000,-. maybe someone can give me a tip or even have my future in the garage! thank you jogo ps: by the way – who needs my rav4 can pick him up by € 1500,- – even has TÜV until May 2011 🙂
