    Had the pre Acert C15 in my 2007 Newell.  Great engine!  I had the Allison transmission which was smooth BUT did not have near the torque the ZF has.  Going up a steep grade you would pull on ahead of someone with the Allison.  Just take to heart what others with the ZF have said on its nuances.

At Newell they shoot for 30 minutes between cycle time.  You can do much better if you spend time looking for all the air leaks and fixing them.  Richard (from the YouTube clip) is an expert at this.  I was only a novice and got mine to only cycle about every 90 minutes when just sitting and not using the air doors.

Loved our Newell but did not fit the type of camping we like to do - too big (weight, length, and height).  Now have a 2004 38' tag two slide Foretravel and fits our type of camping perfectly.  Air only cycles once a day but does have all the air doors.

Good luck,
Oscar
