ST means Special Trailer. Most all are made in China to substandard standards. Basically garbage. There are a couple of decent brands, Maxxis is probably the best of the lot. On the 2002 you will get Frilon siding, a durable product. We had a 2002 19B pull trailer for three years. Good product, but like downtheroad mentioned condition is of utmost importance. Search carefully for signs of leaks inside cabinets, below all windows etc. AF uses an in house made frame, Komfort uses a Lippert frame. IMHO Northwood makes a better frame. Komfort in 04 still made a pretty decent trailer. As there is no longer any warranties either could be a decent trailer, IF it is well taken care of, in good shape, has less than 4 year old tires, and your truck can handle the load.
