When you decide you’re going to build out your van, the first question you’ll have to answer is, “which van should I purchase?” There are lots of important factors to consider when choosing your van, and it depends on your specific needs and reasons for wanting to build your van. You might be wondering:

  • Is the van large enough?
  • What are the interior dimensions of the cargo area?
  • What is the MPG of a Ram Promaster 136WB?
  • Is it easy to drive?

These are all valid questions and some of the things we’ll look at our next article of a series for helping you figure out what van to use as your base. Today we’ll be looking at the Ram Promaster 136-inch wheelbase (WB).

The Ram Promaster 136WB is the most common size Promaster you’ll see out on the road. It comes in three trims; 1500 low roof, 1500 high roof, and 2500 high roof, and can be found with the 3.6-Liter V6 gas engine or the 3.0L EcoDiesel V6 engine. All models are FWD.

How does the Ram Promaster 136WB compare to other vehicles?

The Promaster 136WB is a great size for whatever your plans are for building out a van. If you use the space just right, full time van living in this length will be comfortable. Bumper to bumper, the van is 213”, which is about the same length as a small pickup truck.

The Toyota Tacoma runs around 212” to 225” and the Nissan Frontier ranges from 205” to 219”, so if you are familiar with driving a vehicle this size, the 136WB Promaster will feel just fine. The width and height (if you go with a tall roof) makes it feel larger than it really is, but doesn’t affect drivability.

The 136WB fits in a normal parking spot, and with the tight turning radius, driving/parking the van is a breeze. The backup camera makes life easy if you are in a congested area.

These vans feel bigger because of their width and height. The 136WB comes in two roof versions; low and high. The overall height of the high roof van is 99.4 inches, so a little over 8 feet. The low roof version comes in at 88.7 inches, just over 7 feet. Roof height will be a personal preference, most likely depending on your plans for the van, but both sizes are great options. Some parking garages, car washes, or drive thrus may be off limits with the tall roof, but the low roof may not be the most comfortable if you are tall and looking to do full time van living.

What are the interior dimensions of the Ram Promaster 136WB?

How much space do I actually have to work with in this van? The Ram site has some basic dimensions listed.

What is the Ram Promaster 136WB gas mileage?

Wouldn’t it be nice if commercial vehicles had to reveal the MPG? Anyways, from our research we’ve been seeing the following numbers.

Ram Promaster 136 Gas Engine: 16-18 MPG

Ram Promaster 136 Diesel Engine: 25-27 MPG

These numbers are an average of both city and highway driving. It seems to be in line with what other people are posting online.

Is this the van of my dreams?

It could be! You can pick up 136WB Promasters for about $27,000 – 31,000 brand new depending on the roof height. The average used price seems to be about $22,000, again depending on mileage and roof height. You’ll probably find the best deals on the low-roof 136WB because the market is currently saturated with them – they’re everywhere.

Pros

  • Stealthy
  • Drives like a small pickup truck with a tight turning radius
  • Respectable MPG for the size
  • Interior has almost 90 degree angled walls, easier for van builds
  • Tall roof model allows for most people to stand
  • Cargo area width allows for multiple options for bed setup

Cons

  • Can have issues with driver visibility because the seats don’t lower
  • Not aesthetically pleasing to some people
  • Can be hard to find used in certain areas

I hope this helps you move a little bit closer to finishing that van! Check out the rest of our articles on other commonly used camper van models if you are still deciding on what van to purchase.
