I'm building a brick wood burning heater to heat my pool and hot tub. I've never used wood to heat anything major, so I've never had to buy a large amount of it. I found a place selling 2x4 doug fir mill ends and log ends for 1 cent per pound. Is that a good deal? I know wood is normally sold by volume, not weight. How much does a pickup load of wood weigh? Would I be able to fill up the 8' bed on my truck without overloading it? (about 2500lbs max)
