Can't Comment on the Johnno's, but I love my Camel (Beachcomer Elite SE).
Setup time is pretty quick. Have done a 10,000km trip to NT and back (from Bris) no issues. Camper went really well.
I would have said mine is a 9ft tent? A few mods done, and overall very solid. About to take it to the Kimberley mid-year.
