Does Weight Distribution Hitch Recommendation Change Based On If Fresh Water Tank Is Full VS Empty?

Question

Question:

Hi. I have a question about tongue weight sizing on a weight distribution hitch. Is it better to over the rated weight or under? My fresh water tank, for instance, is located in front of my trailer’s axles and it’s about 40 gallons. I very rarely fill it when I tow. So should I include that weight and have the system oversized most of the time? Or not include it to have it correct most of the time, but undersized when I do carry water?

Hey Russell, that's a really good and tricky question actually.

So, you definitely want to stay within the weight rating of the weight distribution hitch for the best and safest experience. It's not ideal to go over or under. The fresh water tank will likely affect the tongue weight, but I don't think it will affect it quite as much as you're thinking. Since it is tucked behind the front nose of the trailer, and not actually on the tongue section, it shouldn't completely change what WDH is needed just based on it being empty or full.

I highly recommend getting a tongue weight scale such as # BTBRV004 so you can see what the tongue weight is when tank is empty vs full, and find a system that works with both weights. If you can let me know, or at least tell me what your travel trailer weight is or the model, I can find a system that will be good for you. Typically, a WDH has a decent range to accommodate for variations such as the water tank dilemma you are facing.

If you want to make absolutely sure you're going to be fine, I'd get the high quality B&W Continuum Weight Distribution System w/ Sway Control for 2" Hitch # BW78FR which has a huge tongue weight range 600lbs - 1,600lbs (also available in 2-1/2" version # BW28FR). Let me know what you think Russell!

Hey Tim, thanks for reaching out! The .75" sag you're seeing is acceptable, that will not have much of an effect on drive quality at all. If you'd like to totally level out your ride, then add the Air Lift LoadLifter 5000 Ultimate Air…

Hi Kendrick; according to Air Lift the LoadLifter 5000 Air Helper Springs #AL95QF do not fit the TRD Pro models. However, we have had at least two customers successfully install them on the 2023 and 2024. One came back and complained about the impact…

Hey Edwin! If the listed dry tongue weight is 1,330 lbs you will likely be over the rating of your current SwayPro spring bars. You'll probably be adding 150-200 lbs with the propane and batteries, but that does depend on the number of propane…

The B&W Continuum #BW78FR and the Reese Strait-Line #RP66083 are both great systems. The B&W Continuum is going to be easier to set up, but as far as sway control goes, I definitely have to give the edge to the Reese Strait-Line. The…

Hey Lance, That does sound excessive, but the B&W Continuum #BW28FR is a bit of a different animal when it comes to how it operates so I do recommend sticking to the rules laid out by B&W. It wouldn't be a bad idea to have a grease gun…

That is definitely a feature which worries me about the B&W Continuum Weight Distribution System #BW78FR. While there is not a specific measurement I can give you as the bars move up and down depending on the load placed on the bars, B&W…
