I have. It was my second trailer. 19' and when both ends were popped out it was 26'. It's true that you don't have to pop out the ends to be able to use it. You can see that I don't have one end popped out. However, you have virtually no room to walk if you put the couch down to sleep on, and the dinette is pretty short. AND you've got a lot of tent material intruding into the interior.
Remember, you tried a pop-up and didn't like it. A hybrid isn't that much different.
If you think it's easier than a pop-up, it may be -- but only by a little. I was too short to put the bunk ends up by myself and latch them, so I had to be careful where I camped so I could use a pole and step stool to get them up and get them latched on my own. It was tricky, and sometimes pretty dangerous. Those bunk doors are heavy. If I was lucky there was a guy around who could reach them and latch them for me.
Barbie, you're still dealing with more trailer than your Jeep is capable of towing. As Melissa said, the front of ANY trailer apart from true popups create a LOT of wind resistance, and can be easily buffeted around by any amount of wind from either head-on or broadside. When that happens it's up to your tow vehicle to try and keep everything on the road. Your Liberty isn't up to the task.
Please, for everyone's sake, don't think about pulling anything with that Jeep apart from a true pop-up trailer. Aliner, Chalet, Trailmanor -- all of those
might be towable by your Liberty, depending on how big you go.
