Depending on size, the Traeger grill is very easy to store. However, the camp chef is usually the most portable with ease of transport and storage while the big green egg grill has a weird egg shape but a bit compact depending on size. Therefore, depending on your size, you can easily store any of these grills in as little space as you want. Besides, most have wheels for easier movability. As for cleaning, the Traeger grill is easier to clean and maintain, when compared to the other two grills.
Maintenance is an issue. There are moving parts on these grills. Moving parts eventually break. There is an auger with a motor, and a fan with a motor. There are proprietary electronics systems on these babies. Augers clog. Motors burn out. Electronics have bugs or fail. Especially when exposed to rain, snow, hot, and cold. When they fail, will the manufacturer have a replacement part?
I purchased my unit new this last weekend, and had the privilege of working with the owner directly. Extremely polite and informative gentleman who is straightforward and wants you to buy what you think is best. He was not pushy at all and doesn't need to be. The product sells itself. I have a friend who has a Traeger and I have grilled/smoked with him on several occasions. There is a reason this grill weighs significantly more than the Traeger. If you are truly going to invest this amount of money in a grill, please make sure you are completely happy with your investment by purchasing this Yoder grill.
Pellet grills preheat quickly, so you can start cooking almost immediately, and the pellets are available in a number of woods, for different smoke flavors. The smoke has a subtle wood-fired flavor with less of the acrid flavor that comes from standard wood or charcoal. For the maximum smoke flavor, it’s best to cook at a temperature lower than 250 degrees, while higher temperatures cook faster with less smoke.
