Joining the Diesel world

Good advice from the others. I would add one CRUCIAL suggestion: be very careful getting fuel. You have years of training getting gas, and if you allow yourself to hit the pumps on autopilot, one day you will accidentally fill up with gas instead of diesel. So pay close attention, and NEVER let anyone else fill your tank. The diesel forums are full of folks who did one or the other and now regret it. If you ever do find yourself in that situation, DO NOT START THE ENGINE. It only costs a few hundred bucks to drain and dispose of the tankfull of diesel/gas but if you start the engine, now you also have to flush the lines and replace the filter and possibly replace several thousand bucks worth of expensive pieces. All can be a avoided by paying attention. You are going to love the new truck and the way it drags your trailer up mountains.
