Great to hear your trailer is back on the road Steve. Time to plan your next trip!
I know this thread has come to an end but I'd like to mention a couple of things.
Firstly, I have a GAC Wollemi but did not get the off road upgrade until 10 months after purchase. The standard specs have changed a tad since my purchase and I should probably have had the 8 leaf spring and 50mm axle from the beginning. That said, and yes I'm only a novice to the CT scene, I have exclusively camped in caravan parks to give me time to understand our new 4x4, trailer and their capabilities before setting off on our trip to the Kimberly next year. Whilst we have travelled over 7000 kms with our trailer, I have yet to take it off road. We've used it heaps and have a good understanding now of it's workings.
Great Aussie Campers was still a relatively new business and was improving all the time. Could the trailers have come with more detailed instruction? Sure and in time I think the boys would have. That said, the customer has to take some responsibility in learning their CT and it's limits and maintenance requirements. Isn't that part of the fun anyway
Anyway, my 2c worth. We are more than satisfied with our GAC and feel for Claus & Shane like others. Well done on all your hard work fellas and good luck for your next venture!
