One tent quiver
If you only want to spring the money for one decent tent for both backpacking and car-camping this is a must. Splitting the weight of the tent between 2 or 3 people (depending on how cozy you want to get) when backpacking is great and the vestibule provides plenty of extra room for your pack. This is also a great car-camping tent, as it fits a queen size air mattress for when you really want to rough-it. Getcha some!
