Where the 2020 will change, however, is the interior. Shared with the Ram 1500, the interior and all other Heavy Duty pickups will be a significant improvement, with nicer materials, modern style,
and an available 12-inch vertical touchscreen display.
The Ram should also continue to offer off-road–oriented design features like tire tread embossing on the seats and aggressive, red-anodized interior trim. We should see the 2020 2500 Power Wagon debut with the rest of the Ram Heavy Duty lineup sometime next year, perhaps at the 2019 North American International Auto Show in Detroit.
