buddy just purchased a tt with 600 lbs of hitch weight and is curious if a wdh with a higher rating say 1000 lbs would hurt anything or does he need to buy one with the 600 lbs rating?

The bar rating is related to the tongue weight of the fully loaded trailer. I have always preferred to have the next size up of bar, so for 600 true lbs of tongue weight, I would go for the 800 to 1000 lb bars. I bought a new hitch for my new trailer, that has a tongue weight between 400 and maybe 700 lbs, and I find the 600 - 800 lb bars I bought are a little light. It depends on your tow vehicle and hitch as well. 600 lbs on a 2500 series pickup - you can't tell if the bars are on or off. Same deal on a light 1500 series and you need the heavier bars. What the bars do is cut down on porpoising, btw, in terms of ride quality.
Forget the 600 lbs dry hitch weight and plan on the neighborhood of a 1000#. Some actual info would help us give some better advice. Like the trailer GVWR and model number.
