I built a 40 X 48" trailer for hauling apples, supplies, and deer carcasses. I call it "Trailer Two: Electric Boogaloo" because I built it immediately after building the Ninja trailer (the "Trailer Two" part) and Electric Boogaloo rhymes. And I'm very much an 80's kid.
The snowblower tires shown in the pic proved to be not up to the task of hauling 300 pounds of apples into the woods, so they have since been replaced with standard 5.30X12 trailer tires
