Think about the kind of camping that you want to do and when you want to camp. If you envision camping in the boonies or at a resort might dictate the kind of camper you want to buy
What about something like thisMy only issue with a pop up is that I believe it limits you as to where and when you can camp. If you live in the south, that wouldn't be an issue, but cold or wet weather might.
Casita, Scamp or one made in Canada are real lite weight TT that also might work for you, but they are small. I toured a Casita last month and I was really impressed with them.
Fall there are a lot of RV shows going on and I would check them out.
