The Newmar Essex 4533 sits at the top of Newmar's lineup, and owners consistently back that up with words like "best built" and "best equipped." Comfort Drive steering makes the 45-foot coach feel far more manageable on the road than its size suggests, while the Cummins diesel package delivers the kind of effortless highway pull that long-haul travelers depend on. Inside, the 4533's single full bath keeps the floor plan open and living-space generous rather than chopped up. Factory support from Newmar is another point owners single out, which matters on a coach at this level.
