Explore Dump Trailers for Sale at Jayhawk Trailers - Denver, Colorado

If the trailer earns money and your truck and trailer combination is rated over 16,001 pounds, yes. That is Colorado's intrastate commercial motor vehicle threshold under C.R.S. 42-4-235, and the state issues the number with a CO suffix for operations that stay inside Colorado.

A three-quarter-ton pickup pulling a 14,000 pound dump trailer is already past it. Most landscapers and small excavation outfits are surprised by this because they only ever heard about the federal 10,001-pound interstate rule.

Yes. C.R.S. 42-4-223 requires brakes on all wheels once a trailer's gross weight hits 3,000 pounds, and a dump trailer is over that before you load anything into it. Tandem-axle dumps come with electric brakes on both axles from the factory.

Check that your brake controller is matched to the axle count and gain-adjusted for a loaded trailer. Front Range descents punish a controller that was set up empty.

A 7x14 tandem-axle around 14,000 pounds GVWR is the workhorse. With two-foot sides it holds roughly 7 cubic yards level, but weight runs out long before volume does. Damp topsoil is about 2,200 pounds a yard, so three yards of dirt is already 6,600 pounds of payload.

Buy for the heaviest material you haul, not the bulkiest. Guys who size a trailer around mulch end up overloaded the first time they pick up road base.

We stock dump trailers from Load Trail, Southland Trailers, MAXX-D, and Diamond T. Inventory is split between our Commerce City lot and the Truck Center in Fort Lupton, so use the location filter on the listings above to see where a specific unit is sitting before you drive out.

Bumper pull and gooseneck configurations are both in stock, along with low-profile and high-side box options.

Scissor hoists give the most lifting power in the middle of the stroke and handle sticky, heavy material like wet clay and road base best. Telescopic cylinders dump at a steeper angle and clear the box faster with loose material. Dual rams are simple and inexpensive but lose leverage as the bed rises.

If you are hauling dirt, gravel, and demo debris around the Denver Metro Area, a scissor hoist is the safer default.

Yes. Colorado titles and registers every trailer. You have 60 days from the date of purchase to complete registration at your county motor vehicle office, and after that the state adds a $10 per month late fee until you are current.

We send the paperwork with you at delivery so nothing holds up the counter visit.

The magnesium chloride CDOT sprays on Front Range roads does more damage than the loads you haul. It clings to the frame rails, the hoist, the hydraulic lines, and the wiring, and it keeps eating bare steel long after the road looks dry.

Rinse the underside and the box after winter runs, keep the cylinder rod clean and lightly oiled, and touch up scrapes in the bed before they turn into pits. A dump trailer lives or dies on how well the box floor is maintained.
