I have sold 2 of these locations. They service and sell refrigeration units for 18-wheelers as well as work on the trucks themselves. I sold my locations 6000 and 1089 as they have a lot of aluminum to clean on these trucks. I gave a sample of 4501 for them to try out as well. They have a need for these products as well as 615. We got them setup on credit and they use PO's. You will want to talk with the service manager at the locations. Most of the locations are in Texas, but they have 2-3 in Oklahoma, 1 in Shreveport, and a couple in Arkansas. 18-19 locations in total.
