Well, just to report, we made it home safely without further incident.  Now, the damage identification and repair estimates begin.  And the whole hassle of it all....
.....not to mention ever getting my confidence back in driving a motorhome again so I can enjoy the reason I bought it in the first place....relaxation.  I don't want to be on pins and needles every time I pull out of the driveway wondering if I'm going to make it to my destination and be able to make it back home safely.  Not sure how I'll build my trust back.....
You build your trust back by just going on your next trip and understand that sometimes, stuff happens. 
Those of us that are old enough, and poor enough, grew up with recaps on our vehicles. We got used to blowouts and tread separation. This was back when new tires had a 6-12 month warranty and new vehicles had a 12 month warranty. 
The tires available now are so much better and so reliable that it is really not something to agonize over. Just check your air pressure each morning before you hit the road and then just continue with your trips. 
With the tread separation like you experienced, without the loss of air, a TPMS may or may not have helped.
