Our 28RL is in that 600lb tung weight range (dry) and we are closer to 1,000 lbs. or maybe a little more. I went with the 1,000 Equalizer bars because I want things to flex. No point making the ride uncomfortable and no reason to stress the trailer. Going with a hitch that is rated well above what you will be towing simply causes stresses to occur elsewhere, whether in the cab, or on the trailer frame. Buy a WDH for what your trailer is rated for and don’t go above because it does not add a safety factor. My neighbor has a 28’ Sonoma that is a little heavier than ours towing with the same truck. He’s been using an 800 lbs. WDH for six years and he really likes it.
