Hi Campertrailer
I have a walk up Customline. One of the reasons I liked them is you can spec them up or down depending on your budget. We have a stainless kitchen, water tap in sink and external, full annex, overnight awning, tool box, water tanks, 12V power, etc etc.
Since buying it I have installed an inverter and a diesel heater (SWMBO loves that mod).
I have done over 25,000 kms with it. Up the middle to Darwin, back to Melbourne through central Qld and NSW. Just two months ago I took it to Fraser Island with no dramas. I have done thousands of k's off road and it hasn't missed a beat.
The only negatives I have is that I reckon it might be a bit heavy but it is my first camper so I don't really have anything to compare it with. That said it tows great fully loaded or not. The other thing is setting up the tent can be challenging as it is so high it doesn't just flop over, you need to push it up with one of the tent poles. Once we got the hang of it we can set it up in ten minutes. Add another 10 for the annex but I often pack it up with the annex on which makes it easier. They use a very good quality canvas (15oz I think) which would add to the weight. I am happy with a bit of extra weight with top quality materials though.
Oh and a must have option is the canvas bed cover. It is great if you have to pack up wet. When you get to your next stop you can set up and be in a nice warm and DRY bed every time.
Good luck with your choice of camper.
Cheers
