In chapter 2 of the SUV RVing book, I talk about how using a roof-top tent is an option for SUV RVing. I have no first-hand experience with these and so there’s only so much I can say about them, but I ran across this great article at Adventure Journal about using them from someone who is currently “traveling the planet” in a Land Rover with a roof-top tent on top. If a roof-top tent is something you’re considering, be sure to give the article a read.
Most roof-top tents don’t really appeal to me because they still have most of the drawbacks of a traditional tent (i.e., they’re a pain to set up and take down) but are way, way more expensive than most traditional tents, but I guess I’m just missing something. The hard-sided tents like this or this look simpler and appeal to me more than the style shown in photos in the link above, but they’re also more expensive.
