Two and half hours for the brats should be plenty, especially if you set the temp a bit higher, like 225F. The potatoes depending on size may not finish in 21/2 hrs at 220. When I do ribs, I throw a couple of baked potatoes on the top shelf and they take about 5 hours to get soft. As for the beans, I do baked beans in a 2qt AL pan on the top shelf for 2 to 2.5 hours and that's plenty to heat through and get a nice smoke flavor...if you can go longer, then all the better! Yesterday I did chicken breasts and baked beans at 220F. When the breasts were done (about 1 hour), I removed the chicken and ramped the temp up to 230 for the beans to continue heating. Speaking of baked beans, there's a nice recipe in the appetizers list that I use with good success!
