“The nuances of the industry are very important, and they have a great foundation and knowledge base. QLS has good knowledge in heavy-duty trucks and doesn’t need to be taught on the job.”
“QLS has more of a plan and strategy put together when they come into the plant, whereas other providers are followers and just wait to be told what to do.”
