Not real sure where you are planning on going to. Eddyville is in the western part of the state near LBL and I-24 which runs directly into I-65 in Nashville.
I've travelled on the BG Pkwy for many years, it is a nice road that still does not have real heavy traffic.
Lexington is best avoided if you are in a larger MH. I would suggest going around it on New Circle.
There is a nice park north of Lexington (KY horse park I believe) that is supposed to be nice.
