The detachable front end turns the trailer into a ramp — dozers, excavators, and pavers drive on under their own power. The default trailer for tracked equipment.
An RGN's gooseneck detaches from the trailer, dropping the deck to ground level so equipment loads under its own power — no crane, no dock. That single feature is why almost every tracked machine in North America moves on one: dozers, excavators, scrapers, drum rollers, milling machines. If it drives or crawls, an RGN is usually the cheapest way to load it.
The trade-off is weight and cost. An RGN weighs more than a comparable lowboy, which eats into legal payload, and rates run higher than step-deck or flatbed for the same lane. We quote RGN when the load actually needs drive-on loading or the well height — not as a default. A machine that can be craned onto a step-deck for less, we'll say so.
Above roughly 42,000 lbs of cargo on a standard 3-axle, the move stops being legal-weight and the permit engineering starts: 4- and 5-axle RGNs, jeep dollies, stinger configurations spreading weight across more axles to meet per-axle limits state by state. We pull the per-state axle-weight rules before quoting, because the same load can be a simple permit in Texas and a superload in Illinois.
Booking an RGN move with us means the quote includes the loaded dimensions check, the permit stack for the route, and escort requirements if width or height triggers them. The number you get is the number you pay — line by line, no TBDs.
If the equipment moves under its own power, RGN — the detachable gooseneck lets it drive on. A lowboy without a detachable neck needs the load craned or rolled on from a dock or ramp. For dead loads (transformers, pressure vessels) a lowboy or double-drop is often cheaper for the same well height.
A standard 3-axle RGN runs to about 42,000 lbs of cargo legally. Past that, multi-axle configurations (4-axle, 5-axle, jeep + stinger combinations) spread the weight to meet per-axle limits — practical capacity climbs past 150,000 lbs, but every state on the route has to permit it.
More than flatbed or step-deck on the same lane — the trailer is heavier, scarcer, and often permitted. The honest answer is the quote: rate depends on dimensions, weight, route permits, and escort requirements. We publish how our heavy-haul rates are built — see /how-heavy-haul-rates-work/ — and quote same-day.
