Ive asked to keep it at my buddies but he already has two rigs, kids cars, and the wife's SUV. No room

 

And keep insurance on it just in case the worse happens.

 

Use a fuel Stabilizer for sure and don't ask why but put an old piece screen wire around the tailpipe and use duct tape to hold it in place. Critters can crawl all the way up to engine. I have used steel wool for this also.

I personally would not worry about starting it that can cause problems also. The only thing I ever turned over during storage was race motors when I hadn't loosened all the rocker arms to relive valve spring pressure.

When you return do remove each plug and use a small amount of motor oil in each cylinder. Be sure to turn engine over while plugs are out just to be safe.

 

I am maintaining storage insurance with usaa. Should I put any critter traps around it? My buddy will prolly pull my jeep 6 months out from my return to do some mods and tune up. I was gonna throw a few dollars his way for his time.

I have a long list of mods I'd like done before I come back. Who knows where I will end up for my last tour before I retire.

 

What about rust in the fuel tank? Keep it full or empty?

Obviously a healthy dose of fuel stabilizer would go a long-way, tires and battery will be shot.

As previously stated, use Damp-Rid or something on the interior to keep humidity away, and use some cheesecloth and activated charcoal you buy for fish tanks to absorb moisture and keep it smelling good.

Buy new tires when you get back, dry rot and flat-spotting will happen anyway. If yours are really nice, sell them and put some really ****ty junk-yard wheels on it so you won't care. If it is outdoors, make sure you block the windows to keep the sun from fading the interior.

You can cut out some plywood to fit the window, and roll the window up to make a vent.
Drill a bunch of holes in it, and use some mesh screen to let air flow but keep bugs out.

SeaFoam deep creep might be a good idea after you shut the car down and put it in storage:
"Deep creep is ideal for storing engines because it keeps the cylinders oiled while working to control moisture and prevent rust or corrosion on cylinder walls during storage periods."

It is a moisture dispersant like wd-40 which will keep internal stuff from rusting. Spray it generously though the spark plug holes and crank the motor a few times with the plugs removed to disperse it. Then spray some more in there and put the plugs back in kind of loosely so you can put fresh plugs back in before you crank it up after returning home.

And cover all exposed metal with some sort of rust inhibitor/oil to keep corrosion away. You can degrease the crap out of it when you get back with a can of engine degrease and a hose.
