What is the difference between a 2500 and 3500 series truck?

The differentiating factor between a 2500 and a 3500 series pickup truck comes down to the GVWR (Gross Vehicle Weight Rating) of the pickup in question. 2500 series pickups generally start a little below or right above 10,000 pounds GVWR, while 3500 series pickups start at a GVWR of well over 10,000 pounds, and are typically over 11,000 pounds. This of course is more on the marketing side at this point, rather than specific numbers.

3500 series pickup trucks are also generally used as heavy duty work trucks, while 2500 series trucks are used more commonly by a general consumer that needs a bit more than what a light duty pickup will allow for.

You will also more commonly find 3500 series with a dually setup in the rear of the truck (2 wheels on each side).

How much more can a 3500 tow than a 2500?

The max towing capacity between a 3500 and 2500 can be quite extensive! For example, the max towing capacity of a Ram 2500 is 20,000 pounds, while the 3500 can go all the way up to 37,090. This means the difference is 17,090 pounds between the lower 2500 and the 3500 series truck. Ford is quite similar with a difference in max tow capacity of 14,200 pounds.
