1/87th General brand tandem axle lowboy

This is my interpretation of a General brand type tandem axle lowboy, which is a popular brand out on the west coast to haul logging and construction equipment. The gooseneck is removable, and there is an extension on the front. You'll need to supply the pins for the extension, and to lock the lowboy tongue in place, as 3d material isn't strong enough to support.  There is a tandem axle jeep and booster available as well. These use the regular size semi trailer tires.  Questions? Modelmechanic@gmail.com
