Trail King Lowboy Trailers For Sale in Colorado

Trail King lowboy trailers are built for hauling heavy equipment that sits too tall or too heavy for a standard flatbed. In Colorado, that usually means excavators, dozers, pavers, crushers, and other construction or oilfield machinery moving through mountain grades, jobsite access roads, and mixed highway conditions. Trail King is well known in the lowboy and RGN segment for strong main beam construction, stable ride characteristics, and practical deck layouts that work for daily loading. Many buyers searching this category are looking specifically for hydraulic removable gooseneck designs, also called RGN lowboys, because they make front loading faster and safer for tracked equipment.

The first buying decision is usually capacity and deck configuration. Common Trail King lowboy trailers in this class fall around 50-ton to 55-ton ratings, often with 24-foot to 25-foot-plus well lengths and 102-inch overall width. That setup fits a wide range of mid-size and larger iron without stepping into a much heavier platform trailer. A longer well helps with machine placement, axle weight distribution, and carrying equipment with long track frames or attachments. Buyers should also look closely at kingpin settings, loaded deck height, beavertail design, and whether the trailer has load-bearing fenders, because those details affect how easily different machines can be positioned and how well the trailer scales out.

Axle group and suspension matter just as much as rated capacity. Tri-axle Trail King lowboys are common, often paired with air ride suspension, rear lift axles, or flip axle capability when extra capacity or bridge compliance is needed. Adjustable ride height can be valuable on uneven approaches and steep loading angles, especially in rough terrain or when crossing transitions. Tire size, wheel material, and brake condition are practical inspection points on any used lowboy, but on this brand buyers also tend to pay attention to outriggers, recessed D-rings, traction cleats, and ramp condition because these are the features that directly affect daily usability. Pony motors are another frequent spec in this category, giving hydraulic power for the gooseneck without depending entirely on truck PTO configuration.

Decking and securement details separate one heavy haul trailer from another. Wood deck sections are common and easy to service, while outriggers expand flexibility for wider machines or awkward loads. Toolboxes, flag holders, strobes, and front load ramps all add convenience, but structural condition is the priority. Check the neck area, deck crossmembers, axle alignment, suspension components, and any signs of concentrated stress around the well and transition points. For buyers comparing Trail King lowboy trailers for sale, the best choice is usually the one with the right well length, axle package, and hydraulic setup for the machines actually being moved, not simply the highest ton rating on paper.
