Many years ago we once camped next to 3 women of 3 generations, daughter, mother, and grandmother. They appeared to know what they were doing so I thought they were 'seasoned' campers. Later on in the early evening of the first night the mother was getting water from the spigot in between our sites. She said to me, "we've never done this before, and if it rains, we're never doing this again". It poured that night. So hard there was a small river going through our campsite. We didn't sleep much and were up by 5 am. The ladies in the next site? They were long gone before we got up.
The moral of the story is to borrow or rent first. If you like it, borrow or rent a second time. Then if you still like it, start looking at all your options because by now you're hooked and you'll start to form ideas on how you want to camp.
The other caution is that unless the preteen daughter has a real interest, most pre-teen and teenage kids we've known over the years tend to hate camping unless they were exposed to it at a young age.
The trouble with any of us make a recommendation is that we have no idea how they might want to camp or what kind of vehicle they have, or are willing to buy. My first thought is a tear drop trailer, or perhaps an R-Pod if they aren't used to tents. If a PUP is a real consideration, then borrowing a tent would be my first inclination, renting a PUP second.
