A self propelled vehicle which provides a trailer compartment for transporting horses and other animals and living quarters for humans. A cab has a frame which is connected with the trailer frame by a special connection system that enhances the strength and rigidity of the frame. The cab body and trailer body are welded together with flat steel plates. The vehicle provides a low elevation for the trailer floor to facilitate loading and unloading of animals. Front wheel drive propulsion eliminates the need for a drive line to the rear wheels which would interfere with the low to the ground floor.
