I was going to say exactly that. I had it all typed out, and I chickened out. I started wondering if you would have to add the time it took to get it from 40˚ to 120˚ on the first day, to the time it took to get from 40˚ to 140˚ on the final day, and maybe the time it took to cool back down from 120˚ to 40˚ on the first day. If you add that up, you would be way far over 4 hours.
I don't know if this would be a problem, but I think it is, so I think if I was doing it, and couldn't take the smoker with me, I would just make it in their oven. Maybe somebody else would know more about this, but that's my thoughts on the whole thing.
A Prime Rib is too good a piece of meat to play around with, when you're talking about Danger Zones.
I think to be safe, you'd have to take it to 135˚ the first time, and then figure out how to heat it up on the final day, without making it too well done, and I have no idea how to do that.
Sorry, but that's my 2 1/2 cents,
