Greetings members. New to the forum and Pit Boss. Just moved on to a Pit Boss Navigator 850m from a 12 yr old GMG Daniel Boone. Just finished assembly and ready for initial start up this weekend. Impressed with the parts and assembly so far. Feels very sturdy and smooth. A couple of questions. Advise on the vents on back of barrel regarding how far to open. Does anyone have the side smokebox, if so is it single wall or double? I'm looking at mounting the fold up side shelf to the smoke box. Has anyone thrown in desicant filter in their pellet container to draw moisture away? Thanks for any info you can share. Looking forward to reading the wealth of info from these pages. Cheers.
