I have so many memories from my childhood where we camped in our popup. We had an old 1970's popup that was a no-brand I believe made from a kit. Then we had a 1996 Coleman when I was in High School. I even borrowed that Coleman Popup from my parents after high school for a few camping trips of my own with friends. I loved that Coleman! And setup was easy and it was a step above tent camping!
I started focusing more on my career, marriage and kids and took good 8 years off from camping. Finally, I was able to afford my own camper, but with three kids ranging from 3-6 at the time, we needed some more space, luxury and ability to keep food for a week. Plus, my wife at the time thought vacation was renting a cottage for a week. So I had to compromise and I settled on a hybrid. Well... that wife ended up leaving me.
So now I am married again and have a total of 5 kids with my new wife. (Her 2 and my 3). The Hybrid has three queen bunks and works great holding all our clothing, food and gear for a week. our three oldest kids sleep in a tent and love it, so it frees up some of the space inside the trailer.
I do love my hybrid, but I often think about the ease of a PopUp. Setup would be less time, lighter towing, easier to store, easier to clean etc...
The one thing I noticed when I looked at Popups 4 years ago and today, is that its hard to find the larger floor plans without the commode. To me, this is a waste of space. We never had a toilet in our popup as a kid, I dont think you could even get a toilet in one! But now, all the larger floor plans have a commode.
