I currently own a Chalet LTW A-frame but am getting bored with a-frames and want something with a bathroom. I looked at a 183 and 185 that the local dealer just got in. I liked having a second bed but did not like the wall that protrudes out for the TV etc. The couch thingy in the 185 is too small for an adult. I'm getting a feeling that dealers will not stock the 180 or 181. Someone in another off site forum suggested an Edge unit which also caught my eye.
