In 1989 Mike Walker started building a toterhome for himself with Bill Martin in Council Bluffs, Iowa. Word got around and he saw there was a market for toters and trailers. So Mike started a business called Wild Side Custom Haulers.

Mike soon followed up his toter homes with a complete coach for Bob Miller. This was the first complete coach built on a big truck chassis. Bob's first coach was built on a Mack chassis and still looks great almost 30 years later.

As the market was growing, Mike saw the need for a two-car trailer. Stacking two cars took up all the tire rack space. So in 1990 Mike decided it was time for a different trailer no one else had built before. Mike then built himself a trailer with a lift gate and both cars went in the top.

He had to build it for himself because no one would believe that this would go behind a coach. The rest is history.

After many years of building trailers and coaches for some of the top Dirt Late Model Drivers and Team Owners Mike looked to NASCAR as the next challenge. Mike took the small custom coach and trailer company to the big show, as it's called, and began building 53 ft trailers for some of the top teams in the Cup, Busch and Truck series.

In 2000 Mike gave up 80% interest in the business to Gary Baker and moved the custom shop from Underwood, Iowa to Nashville, Tennessee. This was a move to get the needed financial backing put into place so the business could move to the next level. Unfortunately, this partnership would ultimately not work out.

With a passion for custom top shelf work and a "thinking outside the box" mind that loved to build new and improved products with looks you would never forget, Mike decided to move on. In 2003 Mike started 5150 Race Trailers located just south of Nashville, TN off I-65 where history is being made once again.
