Ram offers a low and standard roof height and 3 different wheelbases: 136", 159", and 159" extended.
Each wheelbase has its pros and cons. Use this information to learn more about the advantages of each Ram Promaster van wheelbase and choose the best Promaster for your van build.
The Promaster 159" and the 159" extended vans technically have the same wheelbase, the extended version offers an additional 15" inches of interior length for your build out. The body of the van ‘extends’ farther back past the rear wheels, which is what creates the extra length of the van.
When it comes to city driving, parking and maneuverability, the 136” wheelbase Promaster is idea and the most common wheelbase for customizing. This wheelbase has a tighter turning radius, fits in standard parking spaces, and is the best choice if this is your second vehicle.
The 159” WB is plenty nimble. The van does (barely) fit in standard parking spots, and, like all Promasters, was designed with city driving in mind. Compared to a traditional RV, a 159” Promaster is far and away the more nimble vehicle. The narrow profile of the Promaster, combined with its safety features and moderate size, allow it to navigate city streets with ease.
Unless you do a lot of city driving and you plan on using your Promaster van as your daily driver, parking and drivability shouldn’t be too much of a factor when choosing a wheelbase for your van.
The longer the wheelbase, the more buildable living space there will be inside for your floor plan. The difference in interior space between a 136” and 159” extended wheelbase Promaster may seem inconsequential at first, but it’s quite a big gap in reality.
