Larger bed in a smaller trailer

[RivetNV]

It had to happen sometime. My first post.

I'm 6'3" and would like a bed at least 78" long and would like it to be a minimum of 54" wide so that my wife and I can sleep somewhat comfortably together. Wider would, of course, be better. We are looking for our first trailer which will be an airstream and would prefer 22 ft. or less. This way we don't need a new tow vehicle (I think) and It will have no trouble fitting in to some of the places we want to go such as National Parks and National Forests. My searches have to come to no avail though I am sure there are other posts about this.

Finally the question: What are some of the creative solutions/ideas that you guys have seen or come up with for having a larger sleeping area in a small place?

We are not locked into a floorplan or year, except that our budget is less than $20K (finished). If you have accompanying photos, all the better.
