I appreciate all the replies. Given the lack of 2020 inventory I think I will order a 2021, I am assuming the only way to find out more info on them is to go to a dealer as Chevy's website doesn't seem to have any updates.
The frame rust is the only thing that is still holding me back. I have been paying close attention to Silverado's in town the last few days and it seems to be hit or miss on the rust. One of the trucks I saw was a 2018 and the frame already looked 10yrs old. I realize it may be cosmetic but a $65K vehicle shouldn't have rust all over the place in just two years. On the flip side I suppose it's better than my wife's F150 that the door locks don't work when its below 30 degrees!
