Have had this offset for a while. Never much liked it because no matter what I did the unit wanted to run 325-350*. No where close to slow and low. I moved on to other cookers but never got rid of her. I just did an air mod and added the above air inlets as they should have been, tried, half hearted to seal the door( the bottom is a radius) . Now the cooker is settling in at around 250 but will spike briefly to 300. Is running steady at around 250* now with the grate air shut off. It’s just a trial run, but is working great so far. I increased exhaust height and added some diffuser plates inside also, but wanted to share that I may have breathed new life into an otherwise unusable slow cooker. Time will tell.
