The team made its debut in 2006 with former Grand-Am driver Michael McDowell running a limited schedule.

With McDowell moving on to Michael Waltrip Racing, Sharp expanded to three teams and switched to running Toyotas, hiring former Scuderia Toro Rosso Formula 1 driver Scott Speed to drive the No.

ESR dominated the season, with Speed winning four races en route to a second-place finish in the championship and Lofton won at Michigan.

With Speed heading to the Sprint Cup Series, ESR gained a reputation of fielding championship-caliber drivers.

Like his predecessors, Lofton moved to Red Horse Racing to run for the Camping World Truck Series title in 2010, while Goess returned for the full season.

Although the team supposedly was preparing to return for at least the Daytona season-opener, Woodard Racing closed down before the start of the 2007 season.

After only 9 races, Goess was released from the team and Sharp was reunited with Lofton, who had sponsorship from CollegeComplete.com and a new crew chief in Daniel Bormann.

Sharp then gave the owners points to Cobb for the rest of 2012 in order to allow the truck to eventually be used part-time if a third driver was necessary.

For 2013, Lofton would reduce his schedule to only a few races, while Gale and Rheem departed for Turner Scott Motorsports.

Max Gresham would run the full schedule for the team, with Truck Series veteran crew chief Gary Showalter.
