The only reason I thought about replacing mine is because im gone many months at a time with the Army up at Fort Drum and if it were to fail up there id be screwed. I dont have the time when Im away to be fixing the XK because of our crazy schedule and absolutely no days off. Plus once a month I still have to drive 5 1/2 hours away near NY City for drill and Id hate to be on the side of the road with an over heating vehicle.
