Ramp door or beavertail is the first decision on an enclosed hauler, and this 2026 ATC ROM 400 answers it with a ramp. The rear ramp door is rated 4,000 lbs and carries a transition flap, which bridges the gap where the ramp meets the deck so a low front end does not catch on the lip. That single detail is why ramp-door trailers get bought by people hauling more than one kind of thing.
A beavertail gives a gentler approach angle for a dedicated race car. A ramp door lets you roll a mower, a side-by-side or a pallet jack straight in and then close the trailer up as a box. If your weekends are not all the same, the ramp wins.
Outside
The .030 black screwless aluminum exterior has no exposed fasteners. Black shows dust more than white and it holds heat, but it hides road film better and photographs well if you are wrapping it. A 24-inch stoneguard takes the gravel that comes off the truck’s rear tires, which is where enclosed trailers actually get chewed up. The 49-inch extended tongue improves balance and gives you turning room, and there is a winch plate for non-running loads.
Inside
White aluminum walls and ceiling against black coin flooring, with black overhead and base cabinets. The Plus Package is included. Four recessed D-rings sit flush in the floor. A 30-amp electrical package, dome light with wall switch and A/C prep are wired in, and an aluminum slide-out step gets you through the Premium Escape Door, which has a removable wheel well so a door still opens with a car parked tight to the wall. Spare tire mounts inside on an aluminum wheel.
Capacity
Two 5,200 lb spread torsion axles total 10,400 lbs of axle rating. Spread axles ride better over expansion joints than a close-coupled tandem and scrub the tires harder in tight turns; that is the trade. Confirm your truck’s rating covers the loaded weight before you tow.
