The two most notable differences from the Crestone design is that we did away with the deck and entry over the trailer tongue by moving the door to the passenger side, and also have put a break in the shed roof rather than carrying it all the way to the back wall. We find these improves three things: distributes weight slightly better, makes towing easier by reducing wind turbulence, and also gives you more head space in the center of the sleeping loft instead of tucking it up in an acute angle corner.
