Camper/Caravan options

Gidday all,

Advice/hints etc

I love my camper but it is getting time to move into a small offroad caravan/campervan. I want to tow it behind what I already have which is the 2003 hilux with a tow weight of 1800kg. This does not have to be a full blown offroad caravan but something that will handle rough dirt roads. There are only 2 of us.
A couple of requirements are A/C, toilet/shower facilities (inside or out), ease of setup (read walk in and a couple of minutes you have the billy boiling and are ready for bed), self sufficient.
Just throw some suggestions at me so that I can put my thinking cap on.


Thanks in advance.
