I may have missed it, but besides the importance of livability via the floor plans - I also feel drivability is important too.
So test drives of both units is important. A tip on this, is to make contact with a salesman in advance. Let him know that you are down between two coaches to choose from. Ask him to be sure the coach you're going to test drive, is properly serviced as far as tire air pressure. (I drove one new coach, and the moment I got up to speed on the freeway, I felt something was not right. Turned around at the next offramp, and back to the dealer. Front left tire was running below 80 PSI, should have been 105 PSI minimum, though the placard said 120 PSI.)
During this test ride, see if you notice the one nod on suspension and handling for the Newmar. Comfort Steer. (I don't think I saw that mentioned in the other posts(?) - but may have missed it. Newmar owners with Comfort Steer, usually give it high complements.) While you may not notice it on a test drive, especially if it is a calm day, Comfort Steer really seems to shine in strong shifting cross winds.)
And yes, both solid coaches, hard to go wrong either way
