The ride is fine to me, but I don't have a huge amount of experience. The Monterey had coil springs with after market airbags, and it rode rough depending on the tire pressure.
The Safari has 2 suspension options, Ellipti-ride and Velvet ride. This coach has the Ellipti-ride, which is basically large leaf springs.
No airbrakes, but it has the "Sultan" package, which included an air pump and some pretty cool sounding air horns. Much better than a Wolo Bad Boy.
I've measured the living room and I think there will be plenty of room for a couple of chairs on the driver's side with the TV cabinet on the pax side.
