Sizing a Blue Ox WDH

I'll be buying a new Blue Ox Sway Pro hitch this week and am unsure which spring bars to get. My loaded trailer has a 740# tongue weight. That would increase a bit the one time a year I travel with full fresh water tanks (90 gallons in front of the axles).

I have the choice of 550-750# bars or 750-1000# bars. Which do you think would offer the best sway control and ride? I'm leaning towards the 1000# bars.

get the 1000# lb bars, then you're always in the clear.

Where did you get the tongue weight? You want the spring bars to be more than the max tongue weight you might ever have. So use 15% of the GVWR of the trailer as max tongue weight. Average tongue weight on a TT is 13%, but some (including mine) have closer to 15% tongue weight.

1,000-pound spring bars would be a max trailer GVWR of 6,667 pounds. If your trailer has GVWR more than 6,667, then I would go for the next size up = 1,500 max TW. A 2017 Jay Flight 26BH has GVWR of 7,000 pounds, so if your older 26BH also has GVWR of 7,000 pounds, then I would go for the 1,500 pound spring bars.

My TT has TW of 650 pounds, and I tow it with a ProPride hitch rated at 1,400 pound max TW. Works great. So I'll bet that a SwayPro with 1,500 pound spring bars would also work great to tow a TT with 1,000 pounds hitch weight.

If those were your only two choices, then I would go for the 1,000-pound spring bars. Blue Ox SwayPro has more sizes than that. They also have 1,500 and 2,000 max TW.

Thanks for the advice all. I ordered the 1000# setup. The trailer weighs 6200# when I travel heavy (without water though) with 740# on the tongue per the CAT scale. I'm looking forward to trying the Blue Ox setup. So far I've had a cheap WDH, a Husky Centerline, and an Equal-i-zer. I'll write up my observations on the bunch when I get the chance.

The CAT scale doesn't give you tongue weight with one pass over the scale. So how did you calculate that 740#? A second pass over the scale without the trailer? Tongue weight is the difference between the combined weight on the two axles of the TV with and without the trailer.

I weighed 3 times at the CAT scale. Truck only, truck/trailer no WDH, and truck/trailer with WDH hooked up.
