I have done some of the mod's on snp, like the extension on my chimmney and i also put a sheet metal the lenght of the smoker bottom "with holes to allow heat and smoke to move" but at the end closest to the firebox i still have a temp difference of 50 degree's from the box end to the other end. I made sure the sheet metal is even in the bottom and also tried to lift the far end higher in hopes that the heat will move to the colder end faster. i hope to smoke tomorrow morning and i am stuck with the difference in temp. any ideas ????? Thanks in advance !!!!!!!!
