About Diederich’s RV Mart

Diederich’s RV was started in 1980 by Tony and Donna Slater as an RV parts and repair business. We then went on to buy and sell used travel trailers and fifth-wheels, we sold our first new k-z Sportsmen travel trailer in the mid 80’s and have been building long-term relationships with our customers and suppliers ever since. We are still selling units manufactured by K-Z Inc, and currently carry the Sportsmen, Spree Connect, Durango, and Sportster product lines. We are a full service dealer offering sales, parts and service for every unit we sell. We are a repair center for all major RV appliances and offer service and warranty work for those components.

We are now a second generation, family-owned business with Rich and Rob Slater continuing to offer friendly and courteous sales and service to all of our customers. We promise that every time you call on us we will do our best to take care of your needs. We would like to take the time to thank all of our loyal customers that have enabled us to continue to offer first class sales and service throughout the years.
