BB TX...as I mentioned above we visually looked at the power cord, both ends to make sure the ground pins were good, we also looked at the pins at butt end of trailer. We had RV park attendant check the post all "looks" good. But I have no idea how to test if there's a short in the cords or in the rig.

Also, as I mentioned it was recommended to us to purchase an outlet tester by our FB group peers, we did, it looks like the one you shared...all the outlets in the RV checked out fine. We are perplexed by this...we just aren't able to find it on our own.
