* Check the sticker inside the driver's side doorjamb. This sticker usually lists the vehicle's specifications, including curb weight.
* Consult your owner's manual. The owner's manual should also provide this information.
* Use a vehicle specification website. Websites like Edmunds, Kelley Blue Book (KBB), or others specializing in vehicle specifications may allow you to search by year, make, model, and trim level to find the curb weight. However, be aware that these websites might not have the exact weight for every configuration.
Without knowing the specific trim level (e.g., SE, SXT, etc.) of your 2005 Dodge Grand Caravan, it's impossible to give you a precise curb weight.
