Decoding RV Model Numbers and Letters: The Ultimate Guide


RV shopping can be an exciting yet overwhelming experience, with the diverse array of models and brands available. One of the keys to understanding an RV’s features and characteristics is deciphering its model numbers and letters. These seemingly cryptic combinations hold valuable information about the RV’s type, size, and features. In this comprehensive guide, we’ll delve into the world of RV model numbers and letters, helping you make informed decisions when selecting the perfect recreational vehicle for your adventures.

1. Manufacturer’s Prefix

  • The manufacturer’s name or prefix is often the first part of the RV model number. This indicates the company responsible for the RV’s design and production.

2. RV Type Identifier

  • The first letter or number following the manufacturer’s prefix typically represents the RV’s type or class. Common designations include:
    • C for Class A motorhomes
    • B for Class B motorhomes
    • C for Class C motorhomes
    • T for travel trailers
    • F for fifth-wheel trailers
    • P for pop-up or tent trailers

3. RV Length

  • The next set of numbers in the model often indicates the RV’s length in feet. However, this can vary from manufacturer to manufacturer.

4. Floor Plan Identifier

  • Sometimes, the model number includes letters that correspond to a specific floor plan or interior configuration. For example, “Bunkhouse” floor plans might be identified by the letter “B” in the model number.

5. Optional Features

  • Additional letters or numbers in the model number might denote optional features or packages. For instance, “LS” could indicate a luxury package, while “HD” might signify heavy-duty features.

6. Chassis Information

  • In the case of motorhomes, the model number may include information about the chassis or engine type. For example, “F53” could refer to the Ford F53 chassis.

7. Year of Manufacture

  • Sometimes, the final digits of the model number represent the RV’s year of manufacture. However, this can be misleading, as it might not necessarily reflect the model year.

8. The VIN Number

  • The Vehicle Identification Number (VIN) is a separate but related alphanumeric code that provides detailed information about the RV, including its origin, model, and more. It can serve as a valuable resource when understanding your RV’s specifics.

9. Manufacturer’s Website

  • To decode an RV’s model number accurately, it’s often helpful to visit the manufacturer’s website or contact their customer support for a comprehensive breakdown of what each letter and number represents.

10. Dealership Assistance

  • When in doubt, your local RV dealership can provide valuable guidance and information on RV model numbers and letters. They can help you understand the specifics of the RVs they carry.


Deciphering RV model numbers and letters is a valuable skill when searching for the perfect RV for your needs. By understanding the information conveyed through these codes, you can make informed decisions about your recreational vehicle purchase. Whether you’re looking for a Class A motorhome, a travel trailer, or any other type of RV, this ultimate guide empowers you to decode model numbers with confidence and select an RV that suits your lifestyle and preferences.
