I'm going with2.3L, 10 speed automatic, 4x4 part time selectable engagement and 3.73 open style rear axle in carbonized gray body color. Adding towing package, modular roof, keyless entry pad and running boards. I'm flat towing and wonder if it requires a base plate or if bumper has tow bar hooks. Does anyone forsee a problems with any of my selections? Only adding towing for resale value.
