## Overview

Built on the reliable ProMaster chassis, this compact Class B delivers the easy driving and tight turning radius that owners consistently praise. The 18-foot length makes it exceptionally maneuverable while still fitting a full bath, and you can expect around 16.5 mpg on the road. The ProMaster's wider interior compared to some rival chassis maximizes livability in this efficient two-person layout.
