Our town has switched to these and other towns use various ones, such as the air-flo one, swenson, tarco, tenco,la rochelle,etc. I do not see why they spend an extra $8000 (or how ever much one costs comapared to the stand dump, with central hydraulics and a plow frame they used to get). They have like 30 v-box spreaders but have ordered all the most recent trucks with them. Does anyone use them? why use them over an undertailgate spreader? our town does not have too many big hills so i don't see why they wouldn't go with an undertailgate spreader.
