In one of Bernardos three workshops we want to carry out several works on our Unimog. Despite this is routine maintenance that Joerg usually does alone oil change, changing oil and fuel filters, and replacing the front brake pads five mechanics jump zealously and helpfully around the truck. Bernardos workshops do not only repair Unimog but everything from motorcar to truck what demands a lot of knowledge from the mechanics. Bernardo has a contract with the Policia Federal to maintain all their vehicles. Furthermore, we change our heater of which the boiler was leaking a couple of weeks ago and we had to weld it. Bernardo refuses to take money for the mechanics hours.
