BAM! Done. I did call Dish after I read hear that the 501 and 510 wouldn't like the current pointing of the dish. They said I could upgrade and do the move (at no charge with new commitment) but they would have to cut a new order, which would likely mean I would need to reschedule the date. Didn't want to do that, so I just did the dish mover, and I'll call and get the upgrade later, perhaps next month when the snow is all melted and ground isn't so soft. (I am currently under no commitments)
Dish van with a gentleman doing installs for over 4 years took care of re-pointing the dish. He was at my new home for about 2 hours, tracking down what wires would go to the locations I needed signal today, and then changing out the LNB and re-pointing the dish for 110/119.
Once I'm in the house a bit longer I'll wire up my OTA antenna, get a few diplexers, then get an upgrade on the receivers and maybe add one more. That should have me with my 622, a 722K with OTA module, and a 211k. For the 211k, another coax run will be necessary as that room currently has zero coax jacks and will be paid for by my son.
