Every inch of the Arc is designed with intention — from the adjustable table to the convertible sleeping space.
The rear sofa converts into the sleeping area, giving the 18C a simple shift from daytime seating to overnight comfort.
The adjustable table creates a flexible surface for meals, route planning or laptop time without taking over the compact cabin.
A portable induction cooktop, sink and compact counter area keep the galley practical without taking over the cabin.
Shower controls and water-management details support the Arc bathroom setup, including the Aqua View SHOWERMISER system.
The RAM ProMaster cockpit keeps key driving controls close at hand, supporting the Arc's compact and approachable driving feel.
With the rear doors open, the Arc shows easy rear access for loading, airing out the cabin and stepping into the layout from behind.
