Pit Boss have made this heavy duty beast as a semi-professional pellet based smoker, and it shows. It’s absolutely massive, with a colossal amount of cooking space and a lot of tech that makes using it a serious pleasure. It’s actually probably too big for most households, but if you need the most cooking space possible, this is the biggest on our list.
Manufacturers advertise this piece of equipment as both a smoker and a grill, but it's best to think of it as a superb indirect-heat convection smoker, not a grill. Most models just don't do as good a job of searing a steak as a charcoal grill or even a gas grill with a sear burner can. You'll sear steaks better on a $20 hibachi than on most pellet smokers.
One of the most common problems people encounter with pellet grills is abnormal temperature fluctuations—the controller is set to 250°F, but the grill is dropping to 200°F then climbing to 325°F. Usually people assume that it's a mechanical issue and either the controller or RTD probe need to be replaced. However, very often the problem is far simpler and the solution far easier.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
