I have had my CG Pro with side fire box for several years now. The only mods I have done is to add the dryer vent inside the main chamber and I installed two new thermometers at grate level. I also have a baffle that I can put in. I have always had a hard time getting the smoker up to temperature when I first start cooking. I start with two Weber chimneys full of standard Kingsford Blue charcoal. I usually dump the first two chimneys into the firebox and then I put the grill grate back into the firebox. I then put my wood on top of the grill grate when I'm ready to start smoking. It seems this only gets me to about 190-200 degrees. Any thoughts?
