Summit Truck Group, Rush Enterprises, and Navistar, in cooperation with fellow Navistar International Truck and IC Bus dealers Southwest International and Kyrish Truck Centers, announced they have reached an agreement to move towards strengthening the Navistar dealership network in Oklahoma and Texas.
Summit has agreed to sell all of its commercial vehicle dealership assets to subsidiaries of Rush Enterprises, Inc. Following discussion, Summit, Rush Enterprises, and Navistar mutually agreed to allow current Summit CEO, Justin Fink, in partnership with Southwest International and Kyrish Truck Centers, to purchase Summit’s dealerships in Oklahoma and its International Truck area of responsibility in the area around Wichita Falls, Texas.
Tentatively, this new dealership group will be branded Peak Truck and Trailer. Fink will become the dealer principal and CEO of Peak Truck and Trailer serving the Oklahoma markets. Fink will also establish the support team for the new dealer group.
Within the next two to three years, Peak Truck and Trailer, Southwest International, and Kyrish Truck Centers intend to merge their respective dealerships into one single business and dealer group serving Texas and Oklahoma. This group will include over 20 locations in major markets such as Dallas, Houston, Austin, San Antonio, Fort Worth, Oklahoma City, and Tulsa.
"The decision to form the new International Truck and IC Bus dealership group Peak Truck and Trailer will be invaluable to regional customers in Oklahoma and Texas,” said Mark Belisle, group VP, Dealer Sales and Operations, Navistar. “The eventual merger of these dealerships will create a powerhouse in the south – attracting the highest quality talent and utilizing resources to provide best-in-class service and support.”
The ownership structure of Peak Trailer is also changing, as Summit is planning to divest its ownership to existing owners Southwest International, Kyrish, and Fink. Bobby Briggs, current president of Peak Trailer Group, is appointed to CEO.
