Watch which ones you get if you go to harbor freight, I got one for my bike when I put the other charger on the Super Duty and it turned out that the battery needed to be fully charged as it was just a float maintainer. No big deal for me since the bike was charged but just a heads up.
Make sure you run the tank of fuel down get fresh gas and add stabilizer while at the station and let it run through the system. Also fill up the tires to max pressure to avoid flat spotting or jacks if it could be a year....
