I am considering purchasing a dump truck with a landscape body and I would like for it have drop sides. While conducting my search I have found a lot of manufactures of dump body's (Monroe, Knapheide, Venco, Rugby, PJ's) and it seems the more I search the more manufactures I find. Where does someone like me who has never owned a dump truck start? This truck would be used on a farm/ranch. As for the truck I am looking at F450 and F550's. Any input is appreciated.
