well since im a newbie. i work in a group that is customer sales order support. so i dont make any big design decisions... for some reason, fire chiefs like to customize their trucks a lot. the options can vary, and since we are the leader in this field, we cater to whatever they want. I can be thrown on anything, but i do a lot with different lighting packages. my design work involves setting up the parts in 3d space, creating any new bracketry or whathaveyou that is required to mount said lights and what not, routing wire harnesses in 3d and then making all the prints associated with the options for the assembler to look at for instructions on how to put it together. most recently i am working on a new high pressure drychemical system, just finished up a front mounted winch, new telescopic worklights, water and foam level light package, new LED beacon's, and driver vision rear mounted camera systems and things of that nature probably more than what you cared for but [thumbup]
