I am unlikely personally to go for one of these. We are happy with our current unit and frankly we need the space and amenities of our more mainstream trailer. I do confess to being intrigued by the innovation shown and the woodwork on these units. I think that this interest on my part is a throwback to our tent camping days, and the luxury these campers offer in contrast to those far more rustic days.
Take a look at the details. Notice the plastic springs under the mattress. That looks like a great idea.
