Just an FYI to anyone looking at this. According to the description Mitch gave, this is probably a 22ft HiLo, not 19. HiLo classifies the length of their trailers based on the "rounded" distance from the tongue hitch to the back bumper, and they didn't have a 21 ft trailer that year. So, based on the model year, it's probably a 2201 Towlite.
