Jeep cherokee, good choice man. I used to have one when I was in highschool. It was a POS but still lasted until 160,000 miles.
My neighbor has one with the 4.0 6 cyl. and has over 210,000 miles.
Change the oil when the spirit moves you and it'll last a long time.
I'm glad to hear you are settling in, and that you like it there.
