Do it! I Bergen pellet grill smoking about 3 years ago with a Traeger and it great. The design of that tailgater is about perfect. Those slider grates need to be foil covered or be prepared for a major cleanup headache. Only use cooking pellets and keep them dry.

So I stopped by the BBQ store and they had one and it managed to climb into the back of the truck and came home with me. Real easy to set up, filled with pellets and now it's cleaning itself at 350 for the next hour. I plan on cooking some bacon wrapped chicken tonight on high heat and then tomorrow doing a slow and low brisket all day,
