Hi - the smoke exits through the back lid. After a couple of uses there is pellet dust there. Plus at smoke mode you can see it. I came from a grill with a stack and this holds up great.
The hole on the bottom is for the pellet dump. Works great. Just put a bucket under there and pull the red lever. Plus if it’s like other pellet grills, part of the air intake system is there too to feed into the firebox. Have not actually looked, but I am about sure that’s how it is. Also, the Searwood is much more “normal” as far as the way the auger, hopper etc work. I was glad to see this. Did not care for the rear hopper on the prior model. Seems like it was a real weak point.
The generic cover I ended up getting was under 30 bucks and fits amazing. I just had to turn it backwards because the hopper is on the right. The cover was to fit a pit boss without a stack of similar dimensions. No logos, nice cordura.
Bottom line is they got my cash base on the design and I am very happy with muh purchase - 6 cooks so far.
