Experiences with …. Road traffic master???

Hello have a question to you ….I am currently driving the C/CE driver’s license with ADR + tank (is paid). Now I was advised that I should then the Industriemeister Kraftverkehr (Kraftverkehrsmesiter) which I myself should pay Master Bafög should hang. I have driven the last 6 years with a 7.5 to all goods. Have experience in Germanywide traffic. I make the C/CE since my employer bought two 40 tonrs and would like to have myself as a driver on it. My question who the road traffic meter is well worth the training would be master then. Currently I am constantly addressed by my instructor C/CE how great this profession is and opportunities …..usw….I am skeptical, however, since I can find no job offers in connection with above mentioned Master letter or very few. Does someone have a KVM degree or do you know someone is the KVM? Would it be great if it could tell a few KVM ́s about their career merit would also interest me ….. As what can you work after … because as a truck driver I do not want to work forever…. Greetings and hope for many answers…
