Loaded to Go to Work.
Yes a Commercial Diver working call out looks like a gypses. In the Gulf of Mexico area you need a good old pickup truck to get to work. I have an expanded cab, you can carry others or put you gear inside. Remember the truck will set in nasty, sun baked, dock parking lots. I don't recommend having a new one.
I have two bags for personal gear. One a back pack, for the times when they can offload you but not your gear: In it a change of close, shaving kit and laptop.
