This trailer is based on a 'homebuilt' type I've seen in numerous photos, and in my travels across Oregon and Idaho. It's got a 20' deck, with a fixed 'S' style gooseneck, and is designed for the buyer to add a wooden deck to it. It also uses normal size truck tires, two hole steel wheel type being appropriate, but any hub design would work fine of course! This is typically loaded via the side, not the back like more modern lowboys, but farmers and loggers will do what they need to however they want to right? Right! It has passed the software checks, but if there's a problem or question, contact me via the designer link, or via email to modelmechanic@gmail.com . Be sure and follow me as a 'designer' to get quick access to my shop and notifications of new products.
