This is about the size I plan to build. Although, I want to get a little closer to 22' if I can without stretching. If I need more room, I'll build a tag trailer for space that I don't want to always drag around with me. I'm even considering International. Something like a 9200 midroof condo. And I think this has just the right number of axles.
Of course, mine will be any color other than white.
With this one though, I'd be a little worried that they didn't leave enough clearance in the back. I'll bet it would be easy to drag.
