I purchased a Traeger Lil Tex 22 yesterday. I “grilled” a whole chicken. It overshot the temperature by nearly a hundred degrees which wasn’t a bad way to crisp up the bird but I was afraid it was going to melt itself down so I shut it down. I was up by 5 this morning to smoke a pork butt for pulled pork sandwiches. My wife’s family is coming over for dinner tonight and time being a concern I fired up the “smoker”. It snowed 12 inches last night so the next hour I was shoveling my walks. Imagine my surprise when I checked on the Traeger and it had shut itself off . The meat was colt to the touch. I read through the instructions to make sure I started it up correctly and I did. I removed the meat and restarted the smoker. It smoked for awhile then quit. The temperature never got above 140. I called Traeger technical support twice and each rep gave me a different answer as to why it wasn’t working. After 3.5 hours I gave up on the Traeger for a more conventional method. I purchased the Traeger for the the set and walk away feature. It let me down!! It is 34 degrees outside today so I will wait until it warms up to try again. Should it fail me again I will sell it for scrap! So far I am not impressed. My wood smoker takes time but it is reliable.
As far as size goes, bigger is usually better when it comes to pellet grills. A large hopper means a longer time you can cook without needing to refill your fuel source. A bigger grill size means more room for a variety of meats or side dishes. Look for at least 700 sq inches of cooking space (that can include the upper rack as well – remember, pellet grills work like convection ovens.)
