Your first decision will be to choose one of the two available engine/transmission combinations. The standard powertrain features a 3.6-liter Pentastar V6, with 280 horsepower and 260 pound-feet of torque, and a six-speed automatic transmission. The optional 3.0-liter EcoDiesel in-line four-cylinder produces 174 horsepower and 295 pound-feet of torque. This engine is paired with a six-speed automated manual transmission and offers B5 biodiesel capability. All 3500s feature 11.8-inch Brembo brakes.
Additional options related to the powertrain are an engine-block heater and a 220-amp alternator, an upgrade from the standard 180-amp version.
Next, you’ll need to decide on body size and features. The 3500 comes with a 159-inch wheelbase but it offers two body lengths. The base length is 19 feet 8 inches (236 inches) with a load-floor length of 12 feet 2 inches (146 inches) and 459 cubic feet of cargo volume. The extended-body version is 14 inches longer at 20 feet 10 inches with a cargo floor measuring 13 feet 4 inches and a cargo volume of 530 cubic feet.
Standard body features include rear doors that swing open a full 260 degrees and a sliding door behind the passenger door. Among the available options are fixed windows in any of these doors as well as a sliding door on the driver’s side that comes with or without a fixed window. Additional exterior options include an upgrade from the standard steel wheels to aluminum ones, daytime running lights, rear-window defroster and power-folding and heated outside mirrors.
Inside, you can add a cargo partition with a sliding window or a wood floor. Seating options offer a double-passenger seat, vinyl upholstery instead of the standard cloth, manual lumbar adjustment for both driver and passenger, and heating for cold winter mornings.
Technology options include the Uconnect 5.0 infotainment system with Bluetooth connectivity, SiriusXM satellite radio, a navigation system, a rearview camera and rear parking assist.
Several option packages offer features not available individually:
- The Cargo Convenience Group includes a cargo net and sidewall tie-down rings in the cargo area.
- The Interior Convenience Group adds a lock to the glovebox, shelf-above-roof trim and a windshield-mounted document holder.
- With the Premium Appearance Group you get fog lamps and a silver grille.
- Available for the extended-body 3500 only, the Winnebago Cargo Group bundles many of the individual options together. It also adds swivel seats and a trailer towing package with 7- and 4-pin wiring harness and a Class V receiver hitch.
