The plot thickens! When my son went out later to tighten all the nuts on the L brackets, he also discovered that the left one had been installed upside down Looking at the owner's manual online shows there's 2 ways to mount the brackets, depending upon your hitch. AND because it was mounted incorrectly, a bolt was directly in front of the emergency trailer brake cable assembly, blocking it from working. SO if (heaven forbid!) my trailer had become uncoupled, the cable wouldn't have been able to pull the brakes because a bolt was in the way! A long story, but when I did the walk-through at the dealership they were shorthanded, a young man who admitted he had never done that before was assigned to do it, and he was the one who noticed that the L brackets hadn't been swapped from the trailer I was trading in on to the new trailer, so he did it (incorrectly, apparently). And I, not inspecting nor knowing about this stuff, didn't discover it until today. Luckily I have only towed the trailer twice back and forth. Oh, my goodness! And thank you to all, my trailer was hitched and measured to be level when the hitch was lowered.
