That is a hard question to answer cos the bloody corrugations at Cape York are unreal you think they will be rough and they are smooth,you think they will be smooth and they shake the s..t out of you and the truck. On the Tele track they where pretty bad cos we couldn't get much speed up because the track is very narrow in places.
We did lose 3 cans of rum ,2 cans of coke and cracked 2 of the 24 eggs we had ,but one bonus the eggs came out per scrambled lol lol.
I did drop the tyre pressure down to 55psi front and rear which helped a bit.
We have done a trip out western Qld pre parabolics and the truck was a rougher ride compared to now.
