I have to bite the bullet and spend the money and get a dump body on the 95 F-450 I have I was going to sell the truck as a regular flatdeck but I decided I will put a dump body on it and use the truck. If things need fixing I will fix them. Now heres the choices I'am looking at a dump flatdeck its the cheapest option and more multi purpose. Second option a 11' mason dump with fold down sides most expensive option but I have the option of side loading with a forklift. Last option regular fixed side mason box 11' probably a 2 yard version. I still want to beable to haul building supplies like lumber and stuff that is forkliftable on the side. I had a job couple weeks ago to pick up 6000lbs of tires for a articulated dump truck. I aways get jobs like that where people want something delivered or picked up besides dirt or trash. So a regular fixed size mason box is not really a option if all I wanted to do is haul dirt then I would probably buy one. So its down to a regular dumping flatdeck or a fold down side mason box both 11' long. Is the fold down side mason boxes really worth it I would be looking at minimum 9000 dollars CND they are heavy aswell for a 11' box you looking at close to 2000lbs on the truck I'am trying to keep the extra weight off the truck the way it sits now with a fixed flatdeck its 8400lbs a fold down side box will probably give the truck a tare weight of 10,000lbs a little too heavy. The fold down mason box has one benefit is it does haul dirt better than a flatdeck with wood sideboards and will stand up better to rocks and abrasive gravel. Now a regular flatdeck its the cheapest option and its lightest option it will be almost 1000lbs lighter thats a big difference if I go with a new flatdeck with a hoist it will probably only be the hoist weight so a 9000lb tare. My main line of hauling is debris from construction sites its not heavy its more bulky than anything else. When ever I do haul debris I have side extensions for my current flatdeck to go from 10" sideboards to another 10"s to give me 20"s which is high enough. Rest of the time I just have 10" side boards on the deck to keep stuff from siding off most loads I can load the truck in a way I don't need the extra 10" boards. The problem arises when I haul gravel 10" side boards are not quite tall enough I get a little spillage driving down the road So what do you think a dumping fladeck a better option for a multi use over a mason box with fold down sides ? I can get a aluminum dumping flatdeck for 7000 dollars CND they are nice decks. The last quote I got for a fold down mason box was around 9000 dollars.
