For ten years we had a Phoenix popup on a Tundra and loved it. It handled like a dream.
So why did we change to a hardside? Four reasons: (1) We wanted a bathroom. (2) We wanted a freezer. (3) Popping and dropping the top was getting to be a hassle. (It was muscle powered.) (4) Getting out of bed in the middle of the night was becoming a challenge. (We were both over 65 when we switched.)
Yes, the popup had more problems with condensation in cold weather. But we could have lived with that.
Now that we have a hardside, we would not want to return to the popup. But we had many happy years in the popup. And it was perfectly fine on a SRW. For the Northern Lite we have now, we prefer a DRW for stability.
