There's a place I take my dogs for a walk that has a gravel parking lot that has an eroded ditch on the side. When driving over it very slowly it causes the right rear wheel to be barely touching the ground. The first couple of times there I put it into 4wd the the jeep just laughs and says what ditch? Yesterday I decided to give the BLD a try instead of 4wd. With the wheel in the off-the-ground position it was spinning slowly. Sure enough, I got a bit more aggressive on the throttle then some more power made it to the left wheel and drove me out of the ditch. BLD = nice feature.
