DodgeMaxx,
I see your question hasn't been answered yet. As you know, the 2006 will not have the DPF (Diesel Particulate Filter regeneration system).
The 2006 was built when the 'real' Monaco was humming along. The Executive was a nicely loaded coach, usually, with the larger Cummins or maybe a Detroit Diesel.
With any used coach, check everything, especially the maintenance records.
I just looked at the REV website and I'm surprised that it appears that there is not a 2017 Dynasty offered, only the 2017 Diplomat. The Holiday Rambler line is full with many coaches and floor-plans. I wonder if REV is going to discontinue the Monaco line?
Good luck and let us know what you decide!
MM.
