I like the much heavier axles, tires and mostly the brakes on a tandem dual 20k trailer.  MUCH better and safer than on a std 14k trailer, but get penalized for wanting to be safer! I appreciate my trailer mfg helping me out with a different sticker. The SD DOT must make a living spotting empty tandem dual trailers being towed by a 1 ton.  This guy spotted me going in the opposite direction and drove like crazy to catch me before I crossed the ND state line a couple hundred yards ahead.
