About tag-along trailers
A tag-along (tag) trailer couples to a truck with a pintle hitch rather than a fifth wheel, so it can be pulled by a dump truck, service truck or heavy pickup. Capacities range from about 10 to 25 tons — sized for skid steers, mini excavators, compactors and paving equipment. Tilt-deck, beavertail and ramp variants change how machines load. It is the workhorse for contractors who do not run a dedicated tractor.
