An other reason for less members, PF vs PH, maybe the reliability and development of pellet pits. They have come a long way since inception. Controllers: 3 position, digital with wild temp swings and finally
PID and more refined digital... Open flame cooking option.... Igniters... More heavy duty construction (most premium pits)... Premium finishes and materials, all led to more trouble free/reliable pits....
Some of us remember the early Traegers with all their problems, that for the most part have been resolved, or there is some sort of a fix thanks for those desperate people that wanted something better...The
pits of today are plug and go with the exception of a few. This has cut down the end user development, where we needed to share our experiences and frustrations with others.
That in my mind that attributes to PF having fewer members than PH... Pellet pits are far more commonplace and accepted now than they were 6 -8 years ago. And that lessens the demand for answers.
