* Check your owner's manual: This is the most reliable source.
* Look at the sticker on the driver's side doorjamb: This sticker often lists key specifications, including bed dimensions.
* Use a tape measure: The most direct method, but requires access to the truck.
* Search online using your specific year and model: Search for "[Year] Dodge Dakota Quad Cab SLT 4x4 specs" on Google or a similar search engine. This might turn up the information on a specifications website or forum.
Keep in mind that the dimensions will usually be listed as length, width, and (sometimes) depth. The width may be different between the top of the bed sides and the wheel wells.
