Camped when I was little a few times, Took our kids camping shortly after returning to the states. Been tent camping last 15 years or so. Bought a pop-up cash last month (at 43), while saving for a nice class A. The plan is be able to part time in it in 2020 (at 50), and hit the road full time in 2025 (at 55). I discovered last time I went tent camping that my back is not as young as it used to be. I needed something besides the ground to sleep on.
Had the little ones in their own tents by about age 4 or 5. My son now a boyscout has been in is own tent from 3 years old. He is in the woods all the time in the summer, and a few times in the winter.
