B84 as its name suggests has a clear 8' x 4' body and will transport 8 by 4 material, but its primary application is for carrying large quad bikes and grass cutting machines economicaly. Like the B64 it is supplied with a ramp door and can have a ladder rack and mesh sides as options. The main diferance apart from the length is that the B84 has an 18mm phenol coated plywood floor as the B64 is all steel.
