Off to college in 2 weeks and won't be home till X-mas (Need Advice on few things)

[Anthony]

Hey guys,

I'm heading out to Boston area to go to college for my junior year in 2 1/2 weeks. I just got my '04 Tahoe in May and it has 82k miles and had a 100+ point inspection by the dealer when I got it(who knows if they really checked it all out) Everything has worked flawlessly (exception: one DDM headlight ballast) and I was wondering what things should I check/change before I leave for the almost 5 months away?

-My Oil was changed in May by dealership and reads 56% left as of today. If it is under 50% Should I change it before I go to college with my step-dad or wait until its at 0% and go to a garage out there?
-My belt squeals when its wet outside (early morning dew/heavy rain) for about 5 minutes then goes away. (searched online and found this can happen with newer belts that are wet) Should I change it before I leave?
-Should I check spark-plugs, any other oils in the engine? (or trust the dealership did the job with the inspection in late May?)
-I have a Superchips tuner (to also check error codes) incase they happen
-Any more input on things to inspect/ use before I go?
-I already posted this thread http://www.tahoeyukonforum.com/forum/showthread.php?t=3153 about how to keep my Hoe clean while there and got great advice, so I hope for the same here

Thanks for anyone helping me with all/one of these questions
-Anthony

I'd change the oil before going. It's easy to check your other fluid levels might as well do it.

Yeah I would change the oil too, a spark plug sway with new wires would not hurt either.
Also you should clay bar and wax the car before you leave and give it a final detailing until you get home again. Repeat the same during Christmas and Spring Break minus the plugs.
