First of let me say I have never had 4X4. I don't go off road and I only use paved ramps. 2002 Dodge Durango 2WD 4.7L V160 Bumblebee 14mpg with boat 18mpg highway no boat. This rig is an aboslute pleasure to use. Never any issues or problems getting in and out of ramps at any of the lakes I go to.

Best of luck,
Bumblebee
