WHO IS REESE?

REESE as we know it came to be from a simple request from TJ Reese’s wife: Be creative and make something to keep a trailer from rocking. In response, Mr. Reese designed the first RV stabilizing jacks. The new creation revolutionized the RV industry, allowing RVers to walk through their rigs without the towables tilting side to side.

Since the first set of jacks rolled off the line back in 1952, REESE has added to its offerings with fifth wheel hitches, pin boxes, custom-fit hitches, towing security products, and more! With proven designs that exceed industry standards, REESE is the brand for all your towing and trailering needs. Make the journey as enjoyable as the destination with REESE.
