The corrugations on that road into Gumlong are terrible -- nearly lost one of my spare wheels, the nut holding one of the the spare wheels on the canopy had completely gone, and we only noticed when we only noticed after we were back on the bitumen, and had parked at the ranger's office, put a new nut on and all was good. Needless to say I have modified the design, and it now has a locking pin.
Then after the ranger's office we drove into Moline rock hole for a swim, then driving out -- notice on the track that someone had lost a awning -- I though that I had found a awning, till I realise it was my awning. All the factory pop rivets had all broken. Yep it had fallen off on the way into Moline Rockhole, we didn't even notice it was missing, till we found it on the track on the way out.
It amazing what corrugations do to your gear
