Surprising Gas Mileage in My 2025 RAM ProMaster 3500! (3,000+ Mile Review)

In this video, I share my real-world experience with the gas mileage of the 2025 RAM ProMaster 3500 Super High Roof Extra Long after driving it over 3,000 miles. I’ll taalk about the fuel efficiency on long highway drives, through small towns, and even the hilly terrain of Central Texas. I wasn’t expecting these numbers, especially with a luggage rack and plastic totes catching wind resistance! Join me as I talk about how this van performed on a recent trip from San Antonio to Florida for disaster relief, what kind of MPG I got on city streets, and how the van handled the Hill Country roads.
If you’re considering a RAM ProMaster for van life or commercial use, this review will give you a solid idea of the fuel efficiency you can expect from this beast on the road. Don't forget to subscribe to Van-ish Life for more updates on our van build, family travels, and life on the road!

I've owned two cars modern enough to calculate fuel economy for me. Both of them overestimated my fuel economy by about 5%.
