Utility trailer recently built with green treated 2" x 12" lumber. The frame is a large boat frame, bolted to this frame is a strong structure of green treated wood, coated deck screws and galvanized bolts/nuts were used in the construction.
Brand new trailer lights, wiring, tires, spare, and trailer jack. Axel bearings were just lubed.
Used this to haul snowmobiles out to WY multiple times. Also ATV and Polaris side by side.
Works great. It does need an alignment done as tires are wearing unevenly.
