Seventeen thousand five hundred pounds of payload on a forty-foot deck. That is the whole reason this 2002 Kaufman 101×40 exists, and it is a class of trailer no bumper pull reaches. Tractors, skid steers, a compact excavator with attachments, or a load of long material that would hang off anything shorter.
Frame and deck
A 12-inch pierced I-beam main frame with 3-inch channel crossmembers on 16-inch centers under 2-inch treated wood decking. Pierced I-beam means the crossmembers pass through the web rather than sitting on top, which keeps deck height down without giving up beam depth. Six-inch channel around the outside with stake pockets, plus heavy-duty safety chains.
Axles and jacks
Two 10,000-pound oil-bath axles on slipper spring suspension. Oil-bath hubs run cooler on long hauls and let you check lubricant level at a glance rather than guessing at grease. Slipper springs are simple and cheap to service, which is what you want on a working trailer. Dual 12,000 lb foot jacks make hooking and unhooking manageable even with weight on the neck.
Buying used at this size
Expect honest working wear. Inspect the deck boards, tire condition, axle brakes and the gooseneck coupler, and confirm your truck’s rear axle and hitch are rated for gooseneck loads near 25,500 pounds. A factory toolbox is fitted for chains and binders.
