How to Determine the Dimensions of Your RV

You can find your RV’s dimensions in one of three ways: using a VIN decoder, contacting a dealership, or measuring it manually.

Use a VIN Decoder

Your RV’s Vehicle Identification Number (VIN) is a unique 17-character code that provides you with detailed vehicle information. You can find your VIN in the following places:

• On the frame rail or behind the hitch hookup
• Stamped inside the door frame
• Located on the manufacturer’s plate or tag near the door or by the driver’s seat

Using a VIN decoder like these from NHSTA, Carfax, or JD Power is one of the easiest ways to find your recreational vehicle’s factory specifications—including make, model, trim, and dimensions.

Contact the Dealership or Seller

With your VIN and license plate number, you can contact the automobile shop or dealership from which you bought your RV for its dimensions. If they cannot give you the exact measurements for your RV model, they can offer the average length and width.

Measure Your Vehicle Manually

Manually measuring your RV is a good choice if you have made modifications—whether you’ve added a new bumper, different wheels, a roof rack, or awnings—as these can affect the RV’s dimensions. Stock measurements from a VIN decoder or dealership won’t account for these changes, so manually measuring with a tape measure is the best way to ensure accuracy. Here’s how to manually measure an RV’s dimensions:

• RV Length: Measure the length of your RV from the end of the front bumper to the furthest point at the back, whether it’s a back bumper or something that extends even further, like a trailer hitch.
• RV Width: Measure the width of your RV from the two widest points on either side, taking into account any side mirrors, awnings, or slide-outs.
• RV Height: Measure the height of your RV from the ground to the highest point of the RV, including any roof-mounted AC units or roof racks.
• RV Door Height: With the door closed, measure from the bottom of the door to the highest point of the door frame.
• RV Door Width: With the door closed, measure from one side of the door frame to the other side of the door frame.

What Size Storage Do I Need For My RV?

Whether you’re storing a motorhome or trailer, knowing the right-sized RV storage unit for your vehicle is essential. Here’s a breakdown of the standard recommended indoor and outdoor storage sizes based on the size of your RV:

• 10×15 Storage Units for pop-up campers
• 10×20 Storage Units for small trailers
• 10×25 Storage Units for small fifth-wheel trailers, mid-sized trailers,
• 10×30 Storage Units for large trailers, Class B motorhomes

To allow for easy access to the trunk and open doors, we recommend leaving 1-2 feet of space between the unit wall and RV. For large recreational vehicles, ask about our covered and uncovered outdoor storage options.
