Troll the net and figure out exactly what you want.
I suggest a 300Tdi as it is the last 'mechanical' diesel and has plenty of power for your needs. It needs timing belts every couple years or so (Dependant on mileage and conditions) but once you do it a couple times, it's as easy as changing spark plugs on a cramped V8 engine.
My truck is 7000# loaded for expedition and the 300Tdi moves that just fine.
Once you decide on pick-up vs. 3-door vs. 5-door etc. let me know and I'll get you one.
