Hi

The Cape will rattle anything loose. Use wired nylocked nuts everywhere.
I have a Tradesman roof rack on the GU, ordered through ARB, with specially ordered legs between the main rack "ring" & the upper "ring" that are only 45 mm high (I think) so it fits in my shed.
So, you can have one made shorter if that helps.

I've done a couple of hours at a time of rough corrugations with my Rhino Sports Racks and basket on and had no problem, not sure how much worse the cape would be though. I don't even use nylox on it anymore, I just use the standard black plastic knobs and it was fine.

Proabally the best thing to do would be to put some silicone over the bolt/nuts/knobs (whatever your using). That way they won't come off as the silicone gives it a little room to move but stops it coming un done. I'd still be checking them every smoko though if its really rough.

But I reckon you'll be alright as long as you don't go tooooo fast and don't have toooooo much stuff up top. (comming from the guy whos the worst offender of both those!) :-P

Its funny what will and will not fail over the corrugations to the Cape. What is most important, which is I am sure obvious to you, check everything every day. I was most concerned about the quick release locks that hold my Thule top box on. Basically friction hold downs. They were no problem but a rack fixed with u-bolts and nylocs began to fail before we ever got to the Queensland border. The U bolts stretched and I was concerned they would fracture if I tightened them up.

Went up to the cape last September with "Algee" and everything rattled loose, the dash, the cargo barrier, the rhino roof rack, the best part was it was so rattly that I couldn't hear the missus talking (not really). You just have to be aware and every time you stop check all items. I got my breathers extended, and used a tarp over the bonnet for the creek crossings, but if I was going in June I would get a snorkel fitted, I had some deep crossings and must say was concerned several times, the others had snorkels.
At the end of the trip we were really overjoyed to get away from the corrugations and please lower your tyre pressure, makes a vast difference.

Once past the Wenlock, why not use the old telegraph road. A lot less courrugations than the main track, and more fun at the creek crossings :-). Once we timed it right and ran into Laura 1 day after the yearly grader run.

I'm sure those corros are much taller than 70 mm. Now you've done it, I'll have to go again (trip no 5) and measure em :))
