We have a 2016 Newmar Baystar Sport 3004 (a one year model) and so far after almost 25k miles the Ford V10 chassis has been close to perfect in regards to dependability. Has plenty of power, can be a bit noisy when going up hills as it down shifts but overall good stuff. On another forum there is a separate section for improving the ride on a Ford F53 chassis ranging from minor to really spending a lot of money. We did the former and are pleased.
We have found the fit and finish superior to what we saw in the similar sized Winnebago. As compared, we found the Winnies a bit blah. I am a bit concerned that the recent buyout, Winnebago will bring the quality of Newmar more in line with Winnebago. Not that Newmar is great at QA, as ours had a number of issues when delivered but they were good at resolution.
Hope this helps.
