That is all I have done, you will more than likely have to charge your batteries when you get home, I had to. My wife didnot run it enough when I was gone. You will hear different opinions on what to do, all I can say is what I have done not once but twice. This last time I did change oil before I left. I use all Amsoil products. I use FPPF fuel treatment products, I have been for about 14 years.
I was nervous the first time I was deployed, I was not sure on how to store my truck. Just use some good common sense.
On my first return from overseas truck ran just fine when I returned home.
This last time truck ran fine also, the only repairs I had to make was replace a fog light lightbulb, and repair drivers side window, the adhesive that held the window into the track had dried out. I think I spent all of $20 on parts the rest was my labor.
Oh yea I still need to give it a good washing, and a set of wiper blades.
