Wow, I have admit that is very cool. My camping is a lot simpler than all that. I could not possibly find any reason to justify the cost of something like the X1 or a comparable foldout unit. If I was in the middle of the Outback for weeks at a time, that might be something to have. Thankfully, that is not the case. My kids are grown and the wife and I do not require that much space. My trailer build is based on a Schutt Military trailer frame. It will be nothing like that. I like simple systems and not many of them. I will not be carrying bottled gas for heating and cooking. Also, I believe that a small inexpensive 120V or maybe 12V refrigerator would also save me a great deal of coin. A big part of my build will be solar. Priorities will be a nice bed to sleep in and someplace to get out of the weather. We do not need much more. The wife would like an inside shower and potty and I'm designing that. I think it's doable even in my limited space. My mom and her husband have a 40 foot 5th wheel trailer that was 75k new. It is like the Taj Mahal of campers. It's like staying in a hotel. Nothing like camping. Of course, they live in it half the year. I want light and simple. All those systems require maintenance at sometime.
These trailers are awesome, if you have the means and the need!
