I have a good friend that has an A-Liner. He bought it used a year ago and we camped with him and his wife a few times last summer. The only complaints that he has are that there is little head room because of the "A" shape (he's 6'2") and it has no waste tanks. He has to place a bucket under the camper where the drain is for the sink. I've never owned a Pop-Up so this may be true of all of them. Not really a complaint but he says the heater wakes him up sometimes but I'm sure this is true in all small campers because you're so close to it. On the plus side, he's mentioned to me that it tows very nice with his Chevy Traverse, it has no leaks, it has a Fantastic Fan (I don't know if these come standard or the previous owner installed it)and setting it up is very easy. He does lock it when he goes out on excursions but keep in mind that ALL campers are easily broke into if someone wants to get in them. personally, I haven't had any issues with my 27' regular camper. I did put Combi-Cam locks (http://www.combi-cam.com/) on my storage doors since all of the standard locks are keyed alike but those can be broken into as well. It just gives me a little extra piece of mind. Other than that, he loves it but he does plan on upgrading to a small regular camper that has a bathroom sometime in the future.
