Yes you can grill on a uds, IF you have the upper u bolts like the Big Poppa smoker kit. I built my own uds but bought the Big Poppa basket. It comes with all the hardware for smoking and searing. ( or grillin ) I start about 3/4 of chimney, get about 3/4 going in the chimney. Basket with diffuser setting in the sear spot. Burgers set up of a bit of indirect. Flipped them and moved to direct. Yummy 2 with cheese for me. Lettuce out of the garden. Onions out of my garden and waffle fries. Money shot? Maybe? Thanks for lookin.
