We are fairly new owners of a Fleetwood Sequoia pop-up tent trailer. We LOVE it. In response to your question about noise, though, I must admit that you pretty much hear anything that's going on in the campground. We just got back from a trip with some friends who own a TrailManor, and they didn't hear nearly what we did. They had much more privacy in that regard.
On the plus side, we were in a beautiful setting, and I felt like I was in a tree house in our TT, with a panoramic view from all angles. Additionally, the TT was super comfortable with breezes and a feeling of openness. The TrailManor got rather warm and felt closed in.
Another point of comparison is using the AC. We've successfully used the AC in moderately hot weather, and it was great. However, when it's really, really hot, the AC just can't keep up in a TT. In the TrailManor, the AC cools it just fine!
All in all, we have a bathroom, full kitchen, heat, AC, and it sets up and breaks down quickly. It's been great both dry camping and with hook-ups. And it costs much less than many other RVing options.
