i live travel in a rv working as a pipliner surveyor, and space is small. Currently I have a 99 k2500 suburban, 02 2500 8.1 6 speed, and 05 2500 Avalanche. I have plenty of tools to work on the trucks, but looking to make a bare bones tool box to use when I get off work and want to work on trucks. I know the basic size sockets and wrenches, but asking what am I or could I be missing. Tired of looking over sockets and wrenches I do not need.
