My truck usually sits about 5 days in front on my apartment while I go to college. When I started it today, I had a decent sized puff of grey exhaust come out, and it continued to be grey for a while. It was fine when I got home, about an hour after driving. I am assuming its just from sitting a little bit. Is that right, or could there be another problem?

it could just be carbon deposits. Buy a can of seafoam and seafoam your truck.

If you don't know what it is, do a search. It basically cleans out the carbon deposits in your engine.

Grey or white could be coolant being burned. Bluish is usally oil and black is fuel. Check your coolant level. You might have a leaky intake gasket.

I get some funky smells when I drive a few of my rides after sitting for a few months. Goes away after some driving.

ive looked at seafoam before, but im not sure i could do it right. Ive also hear that it could ruin your fuel filter. I put in some fuel injector cleaner though

Its normal. My brothers 2000 sat for 3 months before I started it last week. It barfed out all kinds of black wet shit on the garage wall. Its just from sitting alot.
