Three horses is about as much as a bumper pull should be asked to carry, and this 2011 Cimarron sits right at that line. Seventeen feet of box, seven feet wide, seven feet tall. The size is not the reason to look at it. What Cimarron did to the inside is.
The interior is the selling point
Insulated roof. Double-walled and rubber-lined throughout. Three roof vents. Drop-down doors on the head side with protective bars, sliding windows on the hip side. Rubber floor mats underfoot, sealed rear doors keeping road spray and dust out of the horse area. Add all that up and you get a quieter, cooler box than most three-horse trailers of this vintage. Horses that travel badly in a bare tin box often settle down in a trailer built like this one.
Airflow you can actually adjust
Ventilation on a lot of trailers has one setting: open or shut. Here the drop-downs, the sliders and the roof vents all work separately, so a July haul and a February haul are not the same compromise. The bars on the head-side drops mean you can run those doors open at speed without a horse putting its head into the wind.
Tack and running gear
The front tack area carries a three-place saddle rack and a handful of hooks. Underneath are rubber torsion axles and four-wheel electric brakes on 16-inch 10-ply radials, with a spare tire and wheel included. Torsion axles suspend each wheel independently, so one side finding a pothole does not telegraph straight across to the other.
Service history is better than usual for a used trailer. Bearings were packed and the lights and brakes serviced in September 2021. That is documented work rather than a claim, and we will show you the record.

Settle the weight question before you buy. Three loaded horses plus tack behind a bumper hitch wants a truck genuinely rated for it and a brake controller that works. A gooseneck of similar capacity tows steadier at highway speed, and that is the honest trade you make for the convenience of a bumper pull. Dimensions are approximate and we will measure anything you need confirmed. Flat $550 freight to the continental US, 30 days to return from delivery.
