'05 Caravan 4 cylinder?

My normal commute is 17 miles one way at 55 mph. No hills, mountains or
freeway driving involved. In fact, I am almost never on the freeway and
when I am never more than 65. So the question is, is this 4 cylinder
really enough power for such driving, especially with the A/C on? I
usually carry few passengers, but would like a van for occasional bulky
but not heavy loads. Does this engine have any known issues? Any known
transmission issues?Would like to know before buying. Thanks in
advance.
