Sounds about right. My trailer has 12,500 GVWR and I went with 1500 bars. I'm pretty much made out on them. I probably could have gone with the 2,000# bars but it's good enough as long as keep towing with my dually.
The only hiccup I had was the shank didn't have enough radius on the corners to fit my receiver! I had to borrow the dealer's grinder to knock them down to fit. Luckily the remaining powder coat hasn't chipped off. If it ever does I'll just get it re-coated. That was summer 2014 so maybe they've fixed that problem. I also have a very heavy duty class 5 receiver (20k) so the inside radii of the main tube may be larger than on lower class hitch receivers.
