Truck bed swap?

The 2014 Chevrolet Silverado 2500 and the GMC Sierra 2500 are very similar trucks with only minor cosmetic differences. Generally, the beds of GMC and Chevrolet trucks are interchangeable, especially if they are from the same generation. The 2014 model year falls within the third generation of these trucks, which was produced from 2014 to 2018.

For the Extended Cab with a long wheelbase, the bed dimensions should be consistent across both Chevrolet and GMC models. However, it's essential to verify the compatibility by checking the specific model year, bed size, and wheelbase of the replacement bed you're considering.

Here are a few things to keep in mind:

Model Years: For your 2014 Chevrolet Silverado 2500, beds from model years 2014 to 2018 of both Chevrolet Silverado and GMC Sierra 2500 should be compatible. However, it's always a good idea to focus on beds from the same generation and model year range.

Bed Size and Wheelbase: Make sure you're looking at beds that match the same bed size (short bed, standard bed, or long bed) and wheelbase as your truck. In your case, you're looking for a long bed that fits the Extended Cab long wheelbase configuration.

Mounting Points and Features: Check the mounting points, bolt patterns, and any specific features (such as step cutouts or integrated bed liners) to ensure they match your truck's requirements.

Trim and Tailgate: Consider if you want to retain your truck's original trim, tailgate, and other bed-related components. These should ideally match or be compatible with the replacement bed.

Condition: When purchasing a used bed, inspect it carefully for any damage, rust, or other issues that might affect its integrity or appearance.
