We've got a canopy now that I haven't actually used yet. It's a jack off system and takes less than 5 minutes to unplug the 3 wired connections, jack off the back of the ute and drive away.
We bought it to compliment the camper trailer, not replace it. My original plan was to just get an empty canopy but a deal came up that I couldn't refuse. This one has a water tank, kitchen setup, designated area for the fridge and a rooftop tent. I'll use it a couple of times a year when I go out camping with mates but when I go out with the family we'll take the Trackie.
There's a Facebook group called 4wd canopies Australia, great group for inspiration.
