 Welcome to St Louis RV

Welcome to St. Louis RV! We specialize in new and pre-owned motor homes.

Located 20 miles from St. Louis Lambert International Airport in beautiful O'Fallon, Missouri, we pride ourselves in having the largest selection of both new and pre-owned motorhomes and RVs in the St. Louis area. We carry every class and style of RV across all the popular brands. We are also a full service repair and parts dealer for all your motorhome and RV needs.

100% satisfaction is our #1 priority. We will spend whatever time is necessary to make sure you find an RV that fits all your needs regardless of whether you are looking to spend $15,000 or $250,000. Tell us what you want and we'll work with you to find the perfect unit for you. If we don't have what you are looking for, please tell us and we'll help you find it. We have coast to coast relationships and access to 100s of pre-owned motor homes. Our staff will provide a full, in-service orientation with you on all our motorhomes and RVs. We do this to ensure you not only know what you are buying, but also how to use what you are buying. We will proudly offer professional, friendly, and honest answers to each of your questions. We will do whatever we can, no matter how long it takes, to ensure you leave with the confidence knowing you just purchased your dream motorhome.

Every single pre-owned motorhome and RV that comes onto our lot goes through a comprehensive three step process. From top to bottom, everything including the engine, generator, electrical system, and air system is checked by Peterbilt's certified mechanics. We then have our own RV technician inspect each unit inside and out to ensure that everything operates and functions properly. Finally we professionally detail and sanitize every inch of the unit. We want you to leave our dealership with a RV that looks and feels like it is new condition.

We operate our business with integrity, honesty and treat all of our customers with respect. We look forward to earning your business and helping you find the motorhome or RV that fits your needs. Give us a call, e-mail us, find us on Facebook, or come see us and "Let the Adventure Begin".
