Loads like this will stack out to just over a "real" cord to give you an idea. You have to stack high and have the tailgate down if racks are not used on a standard 8 ft bed. These 3 loads stacked out at 3 1/2 cord. What others have said is spot on with a 1/2 cord being in a standard bed, stacked, tailgate up with no mound. Prices always depend on your area, supply and demand thing.
Ouch! Those loads hurt just looking at them! Trucks today ain't built for that kind of use. You are absolutely right about cords of course, 4x4x8 tightly stacked or at the pulpwood mill fresh cut 5000 pounds of pine or 5500 pounds of hardwood last I knew which was a decade or three ago.
Pretty sure we are kin somewhere down the line. My dad figured a pick-up could hold whatever fit in or over the bed. One of my more interesting childhood memories is crossing the Mississippi River bridge, a narrow old high rise, with the front wheels of the pick-up in the air going up the incline hauling sand! The truck would also hold all the watermelons you could stack in an eight foot bed, half ton Fords were tough!
My brother bought a cord of wood from a friend's sons, a little high at the time delivered but what the hell. They backed up with a tossed in load of firewood that didn't reach the top of the pick-up truck bed. Their feelings were hurt when we laughed and ran them off. Been many a year since I loaded firewood to sell so I don't know about late model truck beds but a tightly packed rick(which is defined as a half cord around here) would be about one level of wood above the top of an eight foot truck bed in the seventies and early eighties.
Got to admit I made a minor miscalculation about weight once or twice myself. Bought a salvage yard and the warehouse was crammed with stuff that had been thrown in there, 50x90x20 or 24 feet tall walls and you had to literally climb through it. I had a three-quarter ton camper special, rated 7/8. I routinely toted considerably more. One of the old 300AMP welders and all the extras for a welding truck made it sit level and ride as nice as a Cadillac, which rode nice back then. I started stacking V-8 engine heads on that truck, tight like fire wood. First row was as high over the bed as I could come and still be locked in and no danger of breaking the back glass, tight behind the cab. I started on the second row and noticed the tail end of the truck was sitting down just a little with the weight well centered like that. Stopped that row level with the top of the bed. Went to the local scrap yard, 12,500 pounds tare! Might have been a little overloaded.
Most of the firewood peddlers around here would make two to three cords out of your honest cord.
