Here's link to the top of the line Aliner Expedtion with Dormer and bathroom. I'm not advertising the dealership - it just had what I was looking for. This is a very nice camper - totally "loaded"! It also comes with the much desired Cool Cat a/c - much better and more effective than the 5K a/c that hangs out the side of the older models. I've heard wonderful things about it.
DH and I have a 2012 Classic, which is nice, but the Expedition provides more room, as well as a bathroom and dormer. The dormer goes all the way across the back where the couch/bed is, which gives additional headroom/light. We LOVE the easy set up of our Aliner, as well as being able to tow it with a smaller vehicle, just like a PUP. We tow ours with a Nissan Pathfinder with no sway bar or WDH. Others tow with even smaller vehicles, depending on the Aliner model they're towing (I wouldn't tow an Expedition with anything smaller than what I have). Fair warning, though - they are meant for only two people!
Please feel free to join the A frame group on Facebook. There are a lot of nice and knowledgeable people there!
