Heartland Recreational Vehicles LLC, Elkhart, Ind., was founded in 2003 by a quintet of RV veterans. Their philosophy is lower numbers mean a better market and better dealers. That was one of the reasons why all of them left their previous companies to bring Heartland RV to the public.

The first product created by Heartland was a high-end fifth wheel. The LANDMARK which was aimed at extended-stay RVers who spend a lot of time in their coaches at one location was picked to create first on purpose because it was going to be the hardest to build and they wanted to prove that they could do it and do it right.

Because of the success with the Landmark they were able to introduce the BIGHORN in 2004. From this debut, Heartland doubled its dealer base, and added three new coaches in 2005, the CYCLONE toy hauler, SUNDANCE mid-profile fifth wheel, and the entry level line callled the TRAIL RUNNER.

In 2006, Heartland broke ground on a new 110,000 sq. ft. production facility with a new corporate office structure attached.  By the spring of 2006, Heartland had moved into the Top Ten 5th wheel manufacturers, and by the end of the year were solidly #8 with their eyes toward the #5 spot.  Heartland was again poised for growth and launched the BIG COUNTRY 5th wheel and RAZOR toy hauler.
In the spring of 2007, Heartland introduced the NORTH TRAIL line of laminated construction light weight travel trailers and 5th wheels. Continued growth continued and in 2008 another expansion in a new 80,000 sq. ft. facility to produce NORTH COUNTRY wood constructed aluminum sided travel trailers.  The North Country builds on Heartlands tradition of doing it better and doing things right.  In just a few short years Heartland is now #3 in 5th wheels and closing in fast on being among the top 5 towable manufacturers of 5th wheels and travel trailers combined.

Their goal is not to be a high volume company. Heartland aims to create demand from their dealers and for their dealers, and keep innovations going. With notable technological accomplishments like the Patented improved 88 degree turning radius for extended-cab or short-bed pickup trucks and the development of a universal docking center they have proven year after year that they are well on their way to doing exactly what they set out to do!
