This horse trailer is based on the Bloomers type, and is a tandem axle. Included in the file is a satellite dome, Air conditioning unit (for the roof) and an adjustable hitch that one simply glues in place to whatever height is desired. It does NOT include wheels! I do have a set of three wheels/tires that are compatible, sold seperately, as any decent single tires roughly 25 Inches (real size) in diameter will work. it does NOT have a floor in the main trailer body like it does on the tongue. This is to 1. reduce cost and 2. Allow the buyer to create his own interior! The piece has passed the software checks, and is offered in the frosted detail materials only.
