It is nothing to make a habit of, but 20 footers will ride, all-be-it a little squirrely with that much weight behind the fulcrum point of the bed. The neighbor farm called and said they had some good large oaks suitable to be milled, so I went and grabbed the long ones yesterday and then bucked and loaded the rest this morning. Roughly 16 logs ranging between 16 and 28 inches diameter. A mix of white, red, and pin oak. Payment for the logs is in the form of custom cut fresh lumber from these very logs back to the farmer later this year. Bartering the old school way.
