Kaufman’s Premium model adds several valuable upgrades. In addition to the 6’6" standard interior height of the Deluxe model, we also include rubber torsion suspension axles with premium aluminum wheels and West Lake brand radial tires. An additional upgrade is that the .030 aluminum skin is bonded design for a clean, screw-less exterior look. Your choice of colors is no extra charge. The main frame and tongue are 4×2 rectangular tubing. Crossmembers and wall studs are on 16" centers. The floor is 3/4" Dry Max with 3/8" Dry Max walls. Barn doors or a ramp gate are available at the same price for either setup. The coupler is a 2 5/16" a-frame with an upgraded zinc coated front crank jack. An RV-style factory made side door with piano hinge and “slam latch” as well as a cam lock for added security is included. LED tail lights with LED slim line running lights give you a premium lighting package. Premium Tandem Enclosed Trailers are a great investment that will last you many years.
