Yes, especially with a single axle trailer.
With DW set-ups, the cheaper units will have round trunnion bars (spring bars), the better spring bars will be the square bars. The shank, again, the cheaper ones are "cast steel" the better ones are "forged steel". A buddy of mine showed me his "cast shank" that had broken right in half pulling out of a gas station. I got my set-up online "free shipping" here Reese-Hitches.com
I got the 800lb. square spring bars because my tt. was 550 dry at the hitch. You might go with the 500 or 600 lb. bars.
I think I paid about $450 delivered for WD with 800 lb. square bars, forged shank and ball.
