DW and I got a popup in '99 or 2000 and took a trip from OK to ID and back. The flapping noise of the canvas in wind was bothersome. Hearing the neighbors so clearly through the canvas was also unpleasant. Hearing the bear through the canvas... well, DW swears she will never sleep in a popup again! I also disliked the cranking (we didn't have push-button electric up/down), pulling out the ends and getting slivers from the plywood, messing with all the snaps and other setup details. And everything is stored down low, so one must bend over to get every little thing.
I had an Aliner for a year, too. Same thing with the storage, but setup was fast and easy and the walls blocked sound pretty well (no flapping sounds either, obviously!). I wasn't inspired by the product quality, however.
I want to go back to a molded-fiberglass trailer. Scamp, Casita, Lil Snoozy, Parkliner are some of the brands. They are all sold factory direct, but you can find used ones on Craigslist and elsewhere. They tow just about as easily as the popups. The only setup is leveling and hooking up to water/electric/sewer. It's so nice to be able to park anywhere and hop into the trailer to use the bathroom, fix lunch, or whatever.
Nothing wrong with Trailmanors from what I've heard, either. They are heavier but still tow fairly easy with their low profile.
