Hope the ribs worked out?
By way of an temp variation example I did a rib roast, shoulder of lamb (boneless) and a whole chicken on the Gen 2 Ironwood yesterday with a preheat to 245. Once the meat went in and the temp had settled back up to 245 the min temp recorded was 229 and the max temp 258. However for the majority of the time the temp range was around 235-255, I was using WiFi and the Traeger app so could keep an eye on things much more closely than I normally would.
I opened the door twice once when the lamb was done and once when the chicken was done (use a Meater block) and each time recorded a temperature drop of < 10% with a 5-10 minute recovery time. Traeger shut down was as soon as the rib roast was done.
Other than the fact I normally use C rather than F to monitor temp I would regard these figures as good and typical of an Ironwood cook, conversely when I had a 575Pro there was slightly more variation presumably mainly due to single versus double insulation. In addition the Ironwood is in a much more wind / rain sheltered spot than the 575Pro ever was.
Maybe this info is useful for others worried about temp variation?
