Ultimately, it’s really going to depend on where you want to go camping, and what you need to do when you get there. That being said, there is no car in our mind that is not suitable for camping provided you tailor your needs and expectations.
So for example, if you are looking to bring a big group of friends or your family, a Minivan or truck could be the way to go. It will have the space not only for your passengers (and fellow campers) but lots of space to pack the camping gear, food and other supplies you may need.
These types of vehicles will be limited to parking up in a lot or at the most some very mild off road driving on dry dirt tracks. If you want to go deeper into nature, it could be an idea to go for a SUV or 4x4 style vehicle.
