New here, buying a 2000 SLT 5.9

Hey Guys,
Tomorrow im looking at a 2000 SLT 5.9.
Just wondering if there are any common problems with the rigs that I should look for or be prepared for? Didnt really plan on a Durango but I am getting a great deal on it, so its at least worth checking out,

TIA :)

Sorry for the newbness ;)

I'm not sayin all this would go wrong, but I'd watch out for the fan clutch and A/C, and it'll prolly have a real rough idle and backseat riders may not be the happiest people
