Camping isn't for everyone, even people who love the outdoors. Sleeping on the ground or a constantly deflating mattress with sand all over the tent, waking up to being absolutely baked by the sun and trapped in the heat, and just constantly being sandy is not it for a lot of people.
However, RVs and campers can be quite pricey, not to mention they can just take up a lot of extra room you may not have at your home.
If you have a truck though, you're in luck, because you can actually easily turn it into a camper and finally enjoy the great outdoors in comfort and style.
