I want to know where do you put your grass and leaves from your hopper when you are dumping. Is this going in your trailer or in your truck bed? Can you tell your stategy. When I'm talking about hopper, I'm talking of hopper from grasshopper, big frontmount, walker, etc. Personnally, I don,t really like the vaccuum system on a trailer because I would need an other truck just to pull this... Thanks!
