I was more than happy with our Tambo and it served its purpose really well. It was used off road mainly through the high country on some pretty rough roads but we didn't go dragging it up goat tracks and there was no where we took it that people weren't taking Jaycos/Goldstreams.
Now that we've got a young fella we found there wasn't enough room in the Tambo for all of us plus the dog and after much discussion and going through the pros and cons we've gone and bought ourselves a Outback Dove, the decision to go a Jayco over another CT came down to a few things, but the main one was getting a bigger tent area meant needing more level ground to set up on. Also the wife wants to do more touring rather than 4wding, so easy setup for overnighters was a biggy, we've got the annexe for longer stays if we need more room, and it can still get to places the soft roaders can't.
I used to be of the opinion that CT's were the only way to go, and I'd heard all the horror stories about Jaycos, then I spoke to people who actually owned Jaycos about where they had taken them and what problems, if any, they had and the responses I got back was a few niggling issues that Jayco were happy to fix and a little bit of dust ingress, which is fixable. But they had all taken them to places I thought would only be accessible by CT's without any major damage.
