Cookshack makes electric smokers too, MAK is a metal fabrication 1st and a pellet bbq manufacture 2nd, Hearthland noted, I think Yoder sells a lot more offsets then pellet units, Kuma does stoves, etc...so from just the pellet unit standpoint, the numbers are very skewed...unless you know theses number are just from their pellet unit sales...And I do not know, because they are a private company, as most of these are, so not sure where you are getting your sales figures from, but I would have to say that GMG & Cookshack do more then what you are showing...
