New here with a #3.5D. Eye round roast cut up for jerky and homemade rub applied. I used my dehydrator racks as they are tighter. Put jerky in, temp to 155F for 6 hours, added a second chunk of hickory halfway through as the first piece was almost gone. Turned out great! Did a second batch the next day after it marinaded overnight with Bachan's basic sauce and it was great also.
