Thor Motor Coach is the #1 Motorhome manufacturer in North America*  The shear volume of products allows Thor Motor Coach to offer you higher quality, lower prices, and extensive features.  When it comes to giving you more for your money, no other brand can compare.

Thor Motor Coach was formed when Damon Motor Coach and Four Winds International strategically merged in late 2010.  For over 29 years Damon RV and Four Winds RV have been building many of the most recognized brands of motorized Recreational Vehicles in the world. 
Thor continually strives to be a leader in innovation and have research and development departments working with Suppliers and Sales and Service departments to bring fresh products that ensure you are getting exactly what you are looking for.
Thor Motor Coach has put in place some programs to help ensure customer happiness which includes: 24/7 Factory Direct Support (no one should expect that you only drive from 9 to 5), Gold Star Inspection (every coach driven off the Thor Motor Coach lot needs to pass a detailed 200+ point inspection and road test, no spot checking here!), Rapid Response and Concierge Connection.  The Rapid Response is in place to keep you on the road enjoying your Motorhome for years.  Rapid Response is committed to stocking the necessary parts to get you back on the road quickly if ever you need something.  And, rather than assume that everyone is happy, Concierge Connection was started so that every customer that purchases a Thor Motor Coach receives a personal phone call immediately following their purchase and again after 90 days.
With Thor Motor Coach you can be assured of finding just the right coach to fit your family, and your budget!
