Quote Sent<br>Hi Rus, This is Bill with Brechbill Trailers. I received your inquiry about the side height on the Bwise 7x12 Dump Trailer with 44in. sides. That is as high as they go. You could add a 24in. bolt on extension ($1550) or add wood sides using the stake pockets. Click this link to view your custom quote!
