Barbecue Pellet Hopper Assembly 18" Model

It seems no matter what the brand of pellet grill is, this is the major point of failure. What kind of warranty is there on this?

Will this fit in my Traeger series 34? And if not do you have one that will

Does this come with all the hardware to mount it to a Traeger 34 series barrel?

I have a job box that is 60"x24"x24" i want to turn it into a whole hog smoker, would i need two hoppers and is there any recommendations you can make
