I cook in an AmeriQue.
Do 2.5# lion backs at 235*, for 4 hours 15 min., put ribs in at room temp. I only have my rub on for a maximum of 4 hours usually only about 2 or so. Add more rub right before I put the ribs in the AQ.
When I take the ribs out I double foil them and let them rest for 30 minutes to an hour before we eat!
Keep notes and in a few more times it will be to your liking!
Good luck.
