So, I've identified some of the major RFI generators in the house. Some addressed; some not sure how I'm going to address (like the electro-static air cleaner for the HVAC).
Down the street, I do hear power line noise that the power company is investigating.
But I did move my vertical antenna from the top of the house back down to a fence post 5' above the ground, but about 30' horizontally from the house.
My noise on 20meters dropped from S7 down to S1. Similar on other bands, especially on 80meters where I was at S9 with noise and now down to S1.
I'm really amazed that just moving over horizontally 30' reduced the RFI from the house to the Antenna by that much. I still get the occasional birdie on certain frequencies, but for the most part it is an order of magnitude in difference with the noise.
The only other difference is that the feedline is laying on the ground and not vertical along the side of the house. I don't think we were getting RFI on the coax before because if I put a dummy-load on the end of the feedline, I didn't have any noise. But that is the only two differences with the antenna location.
Scratching my head on this...
