Thumbs up Current X17Z Owner, Future 28DSBH Owner - WD Trunnion Bars Load Advice Needed

Hi all, first time post. Before I get my new camper, a White Hawk 28DSBH, I need to upgrade my WD bars to a higher weight than the ones I am currently using for my X17Z. I have this setup:


I do have the 600 pound bars with this, which was great for the X17Z. The White Hawk has a tongue weight of 590 pounds so I can either get the 800 or the 1,200 bars.

Does anyone have an idea of real-world tongue weight with load, battery, LP? I am thinking the 800 bars, but I need some advice.

My TV is a 2012 F-150 super crew with the Ecoboost. More than enough to pull the camper, it's just specifics now.

Thanks for any advice.

That's the same WDH I have, I am using 800lb bars with my X17Z. If I were going to pull a trailer that size I would definitely go up to the 1200lb bars. Your loaded tongue weight will easily hit around 800lbs.

Wow, so the actual tongue weight is that much higher than the factory rating.

I agree, the 1,200lb rated WDH would be my choice for the 28DSBH (7,500lb GVWR). With a 32ft long TT a 13% to 15% loaded tongue weight (% of loaded TT weight) would be desirable, and even with a moderate (no fluids) loaded TT weight of 6,500lbs the tongue weight range will be 845lbs to 975lbs. If your towing habits are on the heavy side exceeding a 1,000lb loaded tongue weight is very realistic.

RV and WDH manufactures recommend a 10% to 15% loaded tongue weight range.

A 800lb rated WDH would work, but you would have to confirm via a CAT scale under loaded conditions that the TT's loaded tongue weight doesn't exceed the 800lb WDH limit. Many folks towing TT's have found that a 13% and above tongue weight enhances the TV's handling of the longer TT's, especially under less than ideal towing conditions.

Ignore the published UVW and DRY weights. Look for a yellow sticker on the side of the TT for it's actual "Ship Weights". Even though the published UVW is 5,290lbs, the actual ship weight will be higher, and in some cases 475lbs higher on some models.

Welcome to the forum! Yes, the loaded tongue weight will be considerably more then the published tongue weight.
