Since you are so "outside the box" I would have expected your brilliance to intuit what I was doing. Testing voltage under load before plugging in the RV is quite clear. It doesn't need to be explained. And I've been advocating it for many years.
I may be the only one that does check voltage under load (but I doubt that). There are other things I may do that few others do as well. Such as limiting the draw to 80% of the shore power supply. Or treating plugs with deoxit. Or using an autoformer when voltage drops below 107.

Fact is, you didn't say you used a dummy load to emulate the load your rig would put on the supply service once plugged in, in fact I'd bet you're the only one that does. You want to be clear? - then post what you actually mean, otherwise your post is useless. :S
