^^THIS^^ I don't get the heartburn over this at all. It droops a little - so what? I can't imagine a single scenario where this will be a problem during normal use over the lifetime of the vehicle. As long as it functions as designed and doesn't affect alignment in closed position - all good.Thanks for the investigation and fix. While a dumb design with no adjustment I won't be taking out the slack. Really doesn't bother me and I'm unlikely to have much of a load either in the bed or on the tailgate.
Remember, this is an economy vehicle designed with a FLEX bed.
