The tensioning slot was left as is to allow more than the shown configuration for chain runs, but I do agree that as shown it takes away from the strength of the frame. We'll take another look into it.
Those are valid reasons; I should have expected that thought went into the idea instead of laziness. But it definitely sounds like those reasons would still be served by a shortened slot put in the right spot.

We used the same method for mounting our bumpers last year and found it very effective. By having the bumpers inside the frame rails added a good deal of stiffness and made install and removal quick and easy.
That's a sneaky use of your bumpers. Shame and kudos to you. Was that a fortunate coincidence or was it planned?
