The Cargo Trailer Brands We Carry


Aero

AERO is built right here in South Dakota — high-quality enclosed, utility, and cargo trailers built for performance and durability. Our AERO cargo lineup runs SA35 single-axle, TA35 / TA52 / TA70 tandem-axle, and gooseneck configurations, with V-nose construction across the line. Sizes range from 6×10 up to gooseneck 8.5×36, with GVWRs of 2,990, 7,000, 9,900, and 14,000 lbs. We also stock the AERO SnoBear enclosed trailer in 8.5×20 TA52 and GN 8.5×32 builds for ice fishing and cold-weather hauls.

Cross Trailers

Cross Trailers come in two V-nose enclosed cargo lines: the CTB standard series and the ALPHA premium series. We carry CTB models in single-axle 3K (5×10 and 6×12) and tandem-axle 7K (7×14 and 7×16) — plus the ALPHA 7.5×16 V tandem-axle 7K for buyers who want a step up in spec.

Cargo Trailer Service & PartsBrakes, bearings, axles, doors, lights, flooring — our local technicians keep your cargo trailer rolling, and our parts counter stocks the everyday components you need.
