I have a 2012 23P, did not know they made a 24 so they may be the same. After 2.5 years and 29,000+ miles it has been nothing but excellent. Extremely high quality build with lots of luxury features. Great ride and handling - mine is on a 2011 E-350 chassis but not all that much different than the E-450 {which is overkill but not necessarily in a bad way}, on a 24'Class C.
Feel free to PM me if you would like more info on my experience with these fine coaches.
