lets not get to complicated . Treg up , pack up ,make Dust . What ever will be will be . The road will decide how your trip will be . lf you don't want the drama of travel , then stay home . Or go & enjoy .
You can dine out on stories of the road for years , or sit home & wonder what it could have been like . Your call 
that's all good and a fantastic attitude for some

....but when I pull over and see that attitude has been the trip prep attitude then I just grab my family jump back in my prepared rig and off I go.. why should I waste time on my holiday to help others who obv could not have given a rats to try and set their vehicle and camper up properly for the conditions they are travelling.
This whole help out fellow man when outback is great but if my fellow man can't give a rats or is towing something that was clearly not designed for the area, then I am happy to put my hand up as one of those ignorant people who offer no help. (except life endangering of course).
Some things fail no matter the trip prep but that is obv to anyone, like in Mcgirs post, when you can see a bloke has done all he can and put new u-bolts on for the trip given the suspension a full service then that's just plain and simple bad luck and he deserves every help avail. But pull up and see rusted old springs ,bald tyres, overloaded rig and he has no tools ..then I am out of there.
Lonleycrusier- good on you for at least asking the questions and trying your best to set yourself for the remote travel , buy using that attitude it should see you through or at very least allow others to see that you have made every effort which might make them more inclined to help out.
