I agree. Go with the 500s or 600s. I use to tow a 19' and a 25' with my softer suspension sedan and had 1200lb bars. There was lots of flex in the bars and it worked great. When I upgraded to a 3/4 ton truck, the 1200lb bars were nothing more than dead weight. They had no flex to them. After reading on this forum, I learned that I was way overhitched. So I went down to the 800lb bars, much better, but then tried the 600lb bars and was even better than the 800lb bars. Now with the 25', I have the dual cam sway, so having some bend/tension on the bars is key. With 600lb bars, life is good. I have about between 750 and 875lb hitch weight (750lbs by the specs) based on a hitch scale I bought.
I bought my bars off eBay. It's hard to break weight bars, but I suppose it can happen. Also the bars are available online from many vendors and I would feel pretty comfy in saying, buying bars off eBay or new via an online Reese shop would cost less than it would at Camping World.
Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91
