Our Mission:

To be the leader in RV & Trailer solutions designed to meet the changing needs of our customers over a lifetime of use.

Our company was founded by Steve Brenneman in 1999 when he decided there must be a better way to build and sell utility trailers than the one-size-fits-all approach.  He created an all-aluminum base frame and wall structure to be lighter, higher quality and more durable than the steel frame trailers that dominated the market.

The fledgling Aluminum Trailer Company (ATC) chose to compete on value, working with our dealers to develop specialty trailer models that enabled the success of the company for many years.

As we’ve grown, we’ve made use of lean manufacturing principles to greatly improve the cost, quality and manufacturing lead times to remain competitive and set the quality standard for our industry. 

Now, ATC is working hard to better understand the market, and which products and services will delight our customers. We are building and expanding on our knowledge and wisdom gained by developing aluminum platforms and models to create trailer and RV solutions.  Yet, as we change and improve, ATC will always remain focused on our mission to understand our customers, their needs and their desires to support them over a lifetime of use.
