Ram ProMaster Dimensions

When I was deciding which van to buy for my DIY camper van build, I researched the Ram ProMaster, Ford Transit and Mercedes Sprinter. Each one has it’s pros and cons, and ultimately I chose the Ford Transit – but the Ram ProMaster Dimensions for width (being the widest van on the market) really caught my eye because it allows you to sleep sideways and save space on your van layout.

When it comes to choosing the right vehicle for van life, finding the perfect balance between space, maneuverability, and reliability is crucial. Enter the RAM ProMaster, one of the most popular vans in the van life community.

The Ram ProMaster dimensions vary based on model. There are several configurations for this van, and the 2500 high roof is the most popular for van life.

In this article, I outline the interior and exterior dimensions of the Ram ProMaster that are important to consider when planning a van build.

Ram ProMaster Options

There are several different options for the Ram ProMaster van which impact the overall dimensions.

Ram ProMaster Wheelbase Options

The Ram ProMaster is available in 118”, 136”, 159” and 159” extended wheelbase.

Ram ProMaster Height Options

The Ram ProMaster comes in three height options: low roof, high roof and super high roof. The super high roof option debuted with the 2023 model, so if you’re buying a used vehicle this height may not be an option.

The high roof option is the most popular Ram ProMaster for van life, as it allows most people to stand up fully inside the van. However, I expect that the super high roof will become more and more popular now that it’s available on newer models.

FAQs: Ram ProMaster Dimensions

Will a ProMaster van fit in a garage?

Yes, and also, no. A standard garage door is 7 feet tall, or 84 inches. Both the low and high roof ProMasters will fit through a standard garage door. A super high roof ProMaster will not fit into a standard size garage.

Which is better: Ford Transit vs Dodge ProMaster?

Depending on which criteria you’re evaluating, Ford Transit may be a better vehicle than the Dodge ProMaster:

Maintenance: The Ford Transit is known for having better reliability than the ProMaster. The ProMaster is known for having issues with its transmission, even before 20,000 miles.

Comfort: In general, neither vehicle is exceptionally comfortable to drive, but the Ford Transit has gotten better reviews for comfort, especially when driving long distances.

Purchase price: The Ford Transit is the more expensive vehicle to purchase. The ProMaster is cheaper upfront, but tends to cost more over its lifetime (due to more frequent maintenance needs).

Build ease: With its boxier interior, the ProMaster is easier to build out than the Transit. Additionally, the ProMaster sits closer to the ground – a bad thing for ground clearance when off roading but a good thing for entering and exiting the cargo space frequently.
