Through the years, Newells have become taller. You are correct, Newell lists a height of 161" for the current coaches (p50's). I show that was the case at least since the beginning of the 2020 models. FMCA did a test on #1643 and listed the exterior height as 13'1". The 2020P in 2015 was listed as having an exterior height of 13'3". The floorplans that I have don't show the exterior height on them. I am not familiar with the amount of downward travel in the p50 so I am afraid I can't help you with that number. On the pre-2000i coaches you could lower the suspension 3-4" from ride height depending on how the ride height had been set before you started rubbing the outside drive tires on the fenders. That may no longer be a limiting factor on the newer models.

Hopefully someone with a p50 will chime in with their experience. I suspect that owners may measure to the height of different objects on the roof as various in motion satellite dishes would have different heights through the years and even different brands. Radio, cell phone and CB antenna used to be the first thing to drag but they are frequently flexible so of much less concern. Sounds like a conversation with Newell is in order for you as they would be the most authoritative source.
