Semi-off-road caravans are becoming more and more popular as more campers want to explore remote parts of our big brown land. Most semi-off-road designs start with a standard caravan body that has a semi-off-road suspension kit added. They have bigger wheels, tyres, and more ground clearance, as well as a 2 or 3-inch chassis riser, so they can go over rutted roads like dirt or gravel.
