I thought of putting it all on the hitch, would have taken a pretty long stinger to get out beyond the tail gate. The tank use to fit on the 300s back rack and the boom attached to the tank brackets. The 300 with a full tank of water was very light on the front end, hard to steer. I did not want to trailer it, be mighty agrivating to maneuver. They make several sprayers on wheels with much larger capacities if needed. The pioneer is already big enough getting around small areas by itself. I think the pioneer hitch would handle the 25 gal sprayer just fine. Good luck, keep the post going with your set up. You all are a lot better at this stuf than I am. Barry
