I had it lined up on 5000b westeel that already had 5hp fan and Haakas unloading door. Got a severe case of buyers remorse before trailer half unloaded and cxlled. You really need to ask more questions than I did. IE existing fan was going to have to be moved, needed transition that I was going to have to get, and I was going to have to plug hole, even get longer electrical cord. Alternative would have been having ducting around outside of the bin run under Haakas chute that would make it unusable. I thought at price of set up it should have been turnkey and did not end up looking that way. That stiffener issue could even be other thing that did not think of.
