Hokey once again come's with the truth. go the old 4.2 diesel patrols. They are just in your range. bolt ons and knowledge are everywhere. and will handle an absolute flogging offroad.
If you like finesse go a range rover or if you can afford it a disco. but be prepared for random electrical gremlins. and you have to baby them off road for fear of snapping axles, (but much much much comfier and expensive off the shelf items will fix all your problems)
