Hi, we just bought our pop-up, and had our first camping trip over the weekend. Looking for tips and tricks on how to store stuff. Do I add a rack to the top of the pop-up? If so which one? Can a cargo hitch be added to the back of the pop-up? If so how? We have 5 people camping at all times. My wife and I along with three kids (2, 7, and 12 years of age). Any and all information would be great! Thanks in advance!
