Sir, your assumption that I am just taking on tasks without concern for my or other drivers safety is insulting at best. I am a 1994 graduate of Mack University in Detroit. I have worked as a heavy truck mechanic for Olmos Construction. In 1998 I returned to my Military careear and have just retired from 30 years in uniform. I have a proven record of sound decesions and understand torque, materials and center of balance issues. The unit is a 1974 SS trailer not the space shuttle.
