Could you Please embed your video into your post so we can watch it right here, Jeff doesn't want offsite links posted anymore, Thanks!http://www.smokingmeatforums.com/t/143758/off-site-links-please-read
Don't tell Jeff but I did watch your video before I deleted it and it looked like real nice smoke to me, almost a little too heavy.
One thing about propane and smoke, the burner will burn up the smoke so sometimes you can't see it but you can still smell it and it will still add flavor. I added an external firebox to my GOSM so I could use the AMNPS and it comes in the back right above the burner. The first couple times I used it I hardly saw any smoke at all but could smell it. I looked around and read about propane flame burning the visible smoke. If I want to see smoke I take the chip pan rack and cover it with foil, that blocks the smoke from coming in contact with the flame.
