Outdoors RV

Outdoors RV Manufacturing was born in 2009 with the vision of owners Ron and Sherry Nash. Our company focus is to design and build recreational vehicles for the customers who desire to enjoy the outdoors, no matter the terrain or weather.  We call it "mountain tough four seasons camping."


Just like the picturesque mountain valley where our factory is located, the RV adventurer of the Western United States and Western Canada will find beautiful pristine alpine lakes, rugged snow capped mountains, lush rain forests, beautiful desert landscapes, and incredible ocean views to explore. We here at Outdoors RV are proud  RV owners and love the outdoor lifestyle in out many adventures we have had customers tell us that they wished a manufacturer would build an RV that was designed for our backyard versus the industry standard that is designed for the pavement and the 3 summer months.


Outdoors answers the call in designing three different series of RV's, two based on how you camp (backcountry series & mountain series) and one being the premium trim package.


Let you outdoor adventures begin!
