Mike, 5 hours may be a little long. At 225-250*, I would check them at no more than 4 hours. I am usually at 260-275* for baby loin backs and have a really good bend at 3 to 3-1/2 hours. Then I sauce/glaze them twice in 30 minutes.
Jeff's rub really makes a great baby back rib. I use it a lot. I have added a little sweet and taken out a little heat. My family and friends like it that way. I did the same thing to his sauce and I think it's awesome.
What model Maverick is that? I have the 732 and it needs some work. The temps at the cooker are spot on, but the remote does not pick up. It's not really a problem, but I would like to have it when I want it.
Good luck with your ribs. post some pics when you're done. Joe
Joe have you tried turning on the remote/receiver before you turn on the transmitter?
I had the same problem with the Remington thermometer (made by maverick) that I bought. I had to read the directions, and that fixed it. Hope this helps!
