Oh Dear, After niggling the bike gear heads on this site, I have to admit that I have all the bling for Australian 4x4 desert touring

Large vehicles carry more gear so are necessary for long trips but small short-wheel bases are more fun.
There are few stock vehicles that can handle true off-road conditions, so after-market additions are required.
Lift-kit - no more than 2" ( if using roof racks put only lite equipment on top as the C of G shift is one of the main causes of roll over)
Diff-lock ( air operated ) turns any fourbie into a tractor, and allows you to inflate tyres, (reduce to 12- 16 psi when in sand).
Gas shocks and large springs ( ride will be stiffer but will handle the BIG hits )
The only real bullbars are steel, but heavy, anything else is a joke.
Twin batteries and isolator - we do like all our battery draining toys
Long range fuel and water tanks Mongolia is drier than outback Oz
EPIRB - emergency beacon
Engine exhaust inflated car jacks are much better than large steel jacks in sand
Do this and you are unstoppable .
