First the F-250 with about 3/4 cord yes he did post a pic. If you look close you can see where the gas can is sitting at that should be filled with wood. Second the sides do not have wood stacked against them in the pic so I would venture to say about 3/4 cord.
Acutally, yes, the wood is stacked against the side rails. The top rail doesn't have anything stacked against it. There is room for one or two more pieces to stack on each side of each row. The gas can is sitting on the drivers side of the truck. That's why it looks a little low. I can normally get 3/4 cord on without the side rails. If I stack the wood level with the top of the middle rail, it measures 3/4 cord. If I stack it about 2" over the top of the top rail, it's a full cord. You can't see it, but in the picture, most of the wood is stacked even with the middle of the top rail. That little limb hides hides a lot of detail. I still had 6 or 8 pcs left to load on the back row when I took the picture. When it was done, it measured out at 112 cu ft subtracting for the wheel wells. It was my first load with a set of bed rails on. I decided to stop there to see how it drove on the 5 mile trip to the house. It drove fine, so the following weekend I came back and cut a full cord of white oak that had been dropped at the same time.
Oh, and a headache rack is on the list. I'm not concerned about what happens while I'm driving. The wood only has about 3" of travel to build up enough momentum to break the rear window, and only the top row is going to be able to move. If the truck stops fast enough for a piece of stacked firewood to slide forward fast enough to damage the window, then I've hit something significantly bigger than me and that firewood is the least of my problems. That's true whether I'm hauling half a cord, or a full cord. I'm more concerned about a piece taking a bad bounce when I throw it into the truck. That happens from time to time, and I don't like holding my breath when it does.
On my truck, a cord of green wood is about as far as I ever want to go. Like I originally said its real close to what my rear end is rated for. Maybe a little over, maybe a little under. Just depends on the type of wood, and the actual moisture content. However, a cord of seasoned wood is well under what I am rated for.
For those complaining about deisels, I wouldn't buy a new one either. Way too much $$, but that also goes for new trucks in general. Looks like next years base line F150 has a sticker of $38K. No way I'd spend that on a truck, and no way I'd take a shiny new $38K vehicle off the highway. My old truck cost me $4K, and had 170K on it when I got it in '09. I've put 30K on it, and it's getting about 2 mpg better milage than my '94 F150 I6 did at that milage. That off sets the extra fuel cost to make the cost of driving them equal. I need to start working on getting and filtering some WMO in order to cut my fuel bill.
