An inquiry from member Innkeepers got me started on this item.
Apparently in Oz a magazine road test had one issue during their testing of the WK2: during a water fording, water entered the body via the battery compartment drain plugs, which had become damaged during an earlier part of their road test.
Sure enough, the underside of the battery compartment is not protected by skid plates, and the plugs are on a part of the floor that projects downward. One of the plugs bulges down so is especially exposed. If the plugs become damaged (say by a hard rock scrape), they could come loose or be partly sheared off. Then water could get by them into the vehicle.
Yeah, that would be an unlucky sequence of events, but forewarned is forearmed. I'll add some fast setting adhesive to the Jeep tool kit in case repairs are needed on the trail.
Good luck out there!
