Thanks everyone for replying to my post. This is going to be a learning curve but looking forward to it, not only the trip but driving something different. I know in the back of my head Discovery's have a reputation for breaking down. The three amigos' I've heard about, but basically good maintenance and you should be ok. Some good suggestions from everyone too. Spare hoses and belts, tape and wire for emergencies and we all know the one thing you don't pack will catch you out. Just need to pick up a good paper map book, yes I'll resist from a gps, nothing like having a beer and looking at a map book. I'll update once I've finished the trip or if we breakdown somewhere and have to ask for some help, thanks again, great site.
