What are the Differences Between Trunnion and Round Bar Weight Distribution Systems
Question:
Im deciding on a weight distribution hitch with sway control. Besides underhang height of the bars is there any inherent advantage of trunion bars versus round bars. I see trunion bars cost more.

Both round and trunnion bar systems are equally as effective, but a round bar system won't have as much ground clearance under it as a trunnion bar system. This is because the bars attach to the weight distribution head from underneath. If your tow vehicle is a full sized pick-up or SUV, a round bar system would work just fine. If you're towing with a small crossover or a minivan (anything with little ground clearance) you'd definitely want to go with a trunnion bar system.
Round bars work great for most applications. But when trailers start to get heavier with a higher tongue weight approaching 1,500 lbs, trunnion bars would be a better option.
