Sandra, There are endless options out there, so in addition to what Mike has said:
1. What will you be towing it with?
2. What tow rating is your vehicle?
3. How many people are you accommodating?
4. Are you looking for a pop top or full height?
5. Do you need a loo or en suite on board or not?
It will help folks narrow things down a bit, then be prepared for many varied views!

Just remember that driving OFF ROAD is illegal & does huge damage to native vegetation, you must stay on formed roads & tracks. Leave it to the trail bikers.
If you want to buy a gravel/non bitumen surfaced road caravan take your pick from all of the brands that claim that theirs is the greatest.
Surf the internet & lots of forums, you'll be amazed & confused.
