We LOVED our little popup and pulled it behind our Subaru for years. My opinion on this and would give it to anyone who asked:
1. Get a fridge. If it can be accessed without lifting the top, that's much better than not, but those are few and far between.
2. Don't get one with a bathroom/shower. Use a porta-potty for nighttime use ONLY. (The less water, sewer you have to deal with, the better. Available at Walmart for less than $75).
3. Used is more economical and if they don't like it, someone else has taken the depreciation hit.
4. A small popup, about 10 years old, but taken care of shouldn't cost too much - less than $5k.
5. A small popup with go almost anywhere and be pulled by most anything that has a tow package on it.
6. They are just FUN!
