Myal,
I am not sure what kind of wheelin that goes on in OZ or your terrain. Here a 2 wheel drive, with any tires, is in real trouble if you try to take it on true 4x4 trails. I don't normally 4 wheel for the fun of it, I do own two very capable rigs and use them for hunting and fishing. I have been locking hubs for over 20 years and you can improve the perfomance of any 2 wheel drive with a lift, locker in the rear and quality tires but it pales in comparison to purpose built off road vehicles. The pics are from about an hours drive from my house. Chris

I did say
"but no , a 2x4 will not usually keep up with a specially modified offroad vehicle over the exact same track , give some leeway and allowance to negotiate one suited to the vehicle tho , and yeah , both will usually arrive at the same destination .."
I have found it to be true .
I have had isuzu 4x4s , nissan patrols and a ex military dodge m37 power wagon and used to regularly drive toyota troopies for work in the outback doing mine maintinence
FWIW , company vehicles go harder faster haul larger loads and go thru deeper rivers than personal cars EVER do ...
Id pit the old dodge against any of those extreme vehicles , anyday of the week , that was one hell of a truck !! ... but Im aware of the limits of my present car , thats why i said what I did above .
most of the 4x4s in Aus are used to take kids to school , mine got regular work outs in the bush prospecting , and hunting / camping , I didnt modify them other than add big grippy rubber . They did good , OK , a bit more axel swing woulda been nice at times , but this was only when I was doing silly stuff cos I could , not because I *needed* to get thru there .
My current kick is to get to where I used to have to be reaching for low range 4x4 before , in my 2x4 , not always on the same track , but arriving at the same destination , kinda like doing it smarter not harder , tho harder is usually more fun when it comes to rock hopping and mud crawling .
