why 30 yrs old?
I am sure you have a good reason but I can't think of any off the top of my head.
If you are sticking with the age limit then we are talking 1980 and older...
Well we still need some more info.
How many people?
Do you want to sleep in the rig, on top of the rig (roof tent) or will you hotel/hostel it?
How important is getting way into remote areas off the beaten track (otherwords do you really need 4x4)?
What is your budget?
What is your timeframe before leaving?
I am sure others will have good questions also but this is what we need to know before we can really offer any advice worth hearing.
cigar smoking, wilderness first responding, ham talking night nurse who is overland certified and a fellow of the Royal Geographical Society.....
now everyone say "so what where have you been lately?"
