Stock Trailer Questions, Answered
Should I buy a steel or an aluminum stock trailer?
Steel stock goosenecks are the heavier-duty option and come in lengths from 16′ to 40′ with axles up to 10K, so they suit big loads and hard daily use. Aluminum stock trailers run 16′ to 32′ on 7K cambered axles and weigh less, which means more payload for the same tow rating and no repainting. Both use a treated lumber floor and carry the same 5-year limited warranty.
What lengths and widths do Gooseneck stock trailers come in?
Steel stock goosenecks are built in 16′, 20′, 24′, 28′, 32′, 36′ and 40′ lengths and 5′, 6′, 6′6″, 6′8″, 7′ and 7′6″ widths. Aluminum stock trailers come in 16′, 20′, 24′, 28′ and 32′ lengths, 6′8″ wide up to 32′ and 7′6″ wide up to 28′. Both bumper pulls are 16′ long and 6′ wide, with a 14′ length and 5′ width available as options.
What is the difference between a gooseneck and a bumper pull stock trailer?
A gooseneck hitches over the rear axle of the truck with an adjustable 2–5/16″ (25K) ball coupler, which carries more weight and tracks better on long trailers. A bumper pull uses a 2–5/16″ V-coupler at the rear of the truck and is the simpler, shorter option for everyday hauling.
How many crossgates come standard?
Steel stock goosenecks include 1 crossgate on 16′ and 20′ lengths, 2 crossgates on 24′, 28′ and 32′ lengths, and 3 crossgates on 36′ and 40′ lengths. Aluminum stock trailers include 1 crossgate on 16′ and 20′ and 2 crossgates on 24′, 28′ and 32′. Extra, removable, split and slide/swing crossgates are available.
Can a stock trailer be ordered with a dressing room?
Yes. Steel stock goosenecks can be built with an any-length dressing room with a door, straight or slant. Aluminum stock trailers offer a 4′ dressing room with larger sizes available. You can add horse dividers, saddle racks, blanket bars, and rubber floor and wall mats. More combinations are listed on the Trailer Optional Features page.
What warranty comes with a Gooseneck stock trailer?
Every stock trailer carries a 5-year limited warranty. You can register a new trailer or submit a warranty claim online.
