Ashful
Minister of Fire
I haul my wood (11 cords last year) in a mix of rented trailers, and occasionally in my half ton pickup. I've not yet run into a situation where I run out of space for wood. I always hit the weight limit of the vehicle or trailer, long before I run out of space. I'm usually hauling green eastern hardwoods, most often oak or ash. Dry and seasoned, oak and ash have similar densities, but oak is 30% heavier when green.
