 Whereas one generic box trailer type was available in the 1970s, at least 16 different trailer and truck types are now manufactured by Winross, including package haulers, beverage haulers, dairy, oil, cryogenic, and propane tankers, a flatbed trailer, moving van trailer, drop pup, double pup, and triple pups, and a couple of straight frame non-articulated trucks.Occasionally, special models have been made, like the special late 1950s Sunoco trailer, or the Charles' Chips delivery van.The official website reports that the company abandoned all retail sales to focus purely on corporate accounts in 1978, though the company is openly pleased by collector activities and formed a branch called 'Winross by Mail'.
