Agreed Wayne - as an "extra" theft deterent this works well.
However, as someone who has two dogs that travel with us in the back of the Discovery I find the rear door a real pain compared to the horizontal rear upper and lower tailgate of my old Range Rover.
Problem is when towing you cannot open the door fully as it fouls the raised jockey wheel. This was not a problem on the Range Rover as the lower tailgate, when down, sat an inch or two above the jockey wheel handle.
It is not a huge problem to lower it out of the way - just a chore on long journeys when we and the dogs need a "comfort break".
Somebody said that you can get a jockey wheel attachment that allows the thing to be turned 90 degrees when not in use/towing.
Anyone come accross one of these?
So, Homer and Marge - you are wise to check these points out before you purchase.
