As someone else mentioned, one of the big advantages of (some) popups is being able to park in a standard garage.
DW and I were happy with our popup for ten years. We became less so as we got older.
Our three main reasons for switching to a hardside: (1) Not having to pop or drop the top or switch from travel to dining to sleeping mode. (2) Wanting a bathroom (not a porta-potty). (3) Having a fridge with a freezer. Oh and our hardside is much easier to get into and out of bed – not to mention being able to sit up in bed.
Though our popup had better fuel economy, was much better on bumpy, dirt roads, AND was a dream on the highway, we would not want to go back – though as I mentioned previously, it was a fine choice when we were younger and just graduating from a tent.
