If you're looking for a pickup truck with plenty of space for cargo, the Dodge Ram is a great option. The Ram 1500, 2500 and 3500 models all have rear seats that fold down to provide extra room for hauling larger items.
To fold down the rear seat in a Dodge Ram, first make sure that there's nothing stored under the seat or in the seat pockets. Then, locate the release lever on the side of the seat cushion and pull it to release the seat back from its upright position. Finally, fold the seat back down into the flat position and secure it with the safety strap located at the front of the seat.
Keep in mind that folding down the rear seats will reduce visibility through the rear window, so it's important to be extra cautious when driving with them lowered. Also, be mindful of how you store your cargo so that it doesn't damage or dirties up your truck's interior.
