As you already know I am very curious about your new M1 so I hope do not mind all the questions.
I know this pit is new to you but do you have any idea how often, when smoking with wood, you would have to add wood?
To many questions?? This is a BBQ forum...many of us eat, sleep and dream BBQ. It never gets old :-)
When smoking with wood you can do it 1 of 2 ways.
1) Fill the basket 3/4 of the way with lump and then add a chimneys worth of burning lump on top. Get it going and throw a split of wood to the top. You can go for 4-6 hours with very little intervention. Maybe add a log here and there if you want to add more smoke.
2) Add ONLY one chimneys worth of lit lump to basket. And from there cook the remainder of your cook using splits. I find that I am adding 2 small splits about every 1-1.5 hours when cooking this way.
I am still new to the M1, so perhaps things will change a bit as I get to really know this smoker.
