Big trucks, like the Dodge Ram 1500, aren’t the most efficient for traveling long distances—but at the very least, Dodge tried to strike a better balance with the Mega Cab models. With more cabin space and a larger gas tank, the Mega Cab is one of Dodge’s best options for long-distance traveling.

How big is the gas tank on a 2007 Dodge RAM 1500?

The 2007 Dodge RAM 1500 comes in three different cab configurations that impact whether or not the truck has a 26-gallon tank or a 34-gallon tank—here’s a breakdown:

Regular Cab (3-passenger capacity): 26 gallons

Quad Cab (6-passenger capacity): 26 gallons

Mega Cab (6-passenger capacity): 34 gallons

With a combined fuel efficiency of about 17 mpg, the Mega Cab’s estimated maximum driving distance increases from 450 to 575 miles. In addition to the Mega Cab’s larger gas tank, the second-row seats also get about eight more inches of legroom than the Quad Cab.

These two factors make the 2007 Dodge RAM 1500 Mega Cab a much more comfortable and effective option for long-distance travel than the Regular and Quad cabs—if that’s what you’re looking for, of course.

How to check your 2007 Dodge RAM 1500’s gas tank size

Want to check our work? Here are other ways to check what size gas tank your 2007 Dodge Ram 1500 holds.

Measure the gas tank

If you’re not willing to accept that your gas tank size is connected to the cab configuration of your truck (which should be confirmed by an emblem on the rear), then you can also physically measure it yourself.

First, record the tank's width, length, and height. Then, multiply the dimensions and divide the result by 231 (that’s the number of cubic inches in a gallon). If your measurements are accurate, you should end up with either 26 or 34gallons.

Check your owner’s manual

You may have to wipe the dust off of it after pulling it out of your glove compartment, but your owner’s manual will confirm the size of your gas tank. Look for “fuel tank capacity” or similar phrases in the index to point you in the right direction.

Drive till empty, then fill it up

Want to run a little experiment? Another way to test the size of your gas tank is by driving until your fuel gauge nears empty and then measuring how many gallons it takes to fill it back up.

Of course, if you don’t literally roll into the gas station, the measurement may not be 100% accurate. But that’s okay, because pushing a massive Dodge RAM 1500 is probably the last thing you want to do.

How to save on fuel costs in a 2007 Dodge RAM 1500

The 2022 Dodge Ram can achieve roughly 28 combined mpg, which is quite the improvement from the 2007 model’s 17 mpg. But if you’re not willing to part ways with old trusty quite yet, there are different strategies you can implement to save on fuel costs.

Keep up with maintenance. With proper vehicle care, age is just a number. Routine fluid exchanges and regular inspections can help keep your 15-year-old truck running as efficiently as possible.

Drive carefully. The 5.7-liter V8 engine under the hood of a Dodge RAM 1500 can be quite the gas guzzler if you’re flooring it at every green light—give it a break for better mileage.

Avoid idling, especially in cold weather. Driving your truck gently to warm it up is a much more cost-effective alternative.
