Three axles instead of two, and 44 feet of box. That is the short version of why this 2025 ATC ROM 500 sits where it does in the lineup. The buyers are collectors moving more than one car at a time, race teams hauling a car plus a full pit setup, and anyone whose loads run past what a tandem-axle 40-footer will legally carry. Underneath sit three 7,000# spread Dexter torsion axles.
The third axle buys capacity and it settles the ride. It also means more tire scrub in a tight turn and a longer swing when you back into a paddock spot. If most of your miles are interstate, that is a fair trade. If your weekends involve threading fairground gates, look hard at a 40-footer before you sign for this one. You also need a bed-mounted hitch and a truck rated for the combined loaded weight.
Inside and out
The finish is the Black-Out Package over a .040 black screwless exterior. Walls and ceiling are insulated screwless aluminum, which cuts condensation and knocks down road noise on a long run. The floor is black coin. The gooseneck riser is carpeted in grey, and that riser is genuine storage: it is the natural home for tires, jacks and tool bags you do not want sliding around the main deck. Interior height is approximately 7 ft. 5 in., so measure any lifted truck or tall show car before you assume it clears.
Loading happens over the beavertail. The premium escape door has a removable fender, which is what lets a driver actually open the door after parking a car tight to the wall. Four 5,000# D-rings sit recessed so straps lie flush with the floor. The trailer is wired and framed for a future A/C unit, worth having even if you skip the unit now. Tapered nose, hydraulic jack, rear wing with LED lighting, premium LED electrical, aluminum wheels with a matching spare. Structural warranty runs three years.
