We've used the Andersen Hitch for over 6 years now and am very pleased with it. I think it is accurate to say that the Andersen is not suitable for cases where a LARGE amount of weight distribution is required. However, my trailer has about a 600 lb tongue weight like you, and it is terrific. For people in a similar situation as ours, the Andersen is a great choice. It does provide weight distribution as well as great sway control and bounce attenuation. I can tow without any type of WDH but it is so much nicer with the Andersen. I wouldn't tow without it.
