Features to know about

Know Your Tongue Weight Before You Tow

Tongue weight scale in use

Tongue weight problems usually show up after you are already on the road. This scale lets you check the number ahead of time, so you can load cargo, adjust your hitch, or rebalance before sway or handling issues start.

Clear, Accurate Readings You Can Trust

Backlit digital display

The backlit digital display is easy to read while lowering the coupler onto the scale, even in low light. It measures in 5 lb increments with accuracy within +/-0.5%, so the number you see is one you can rely on when dialing in tongue weight.

Adjustable Height for Proper Coupler Fit

Adjustable height tongue weight scale

Not every trailer sits at the same height. This scale adjusts from 19-1/2" to 27" in 1-1/2" increments so the coupler settles naturally onto the scale instead of forcing the jack higher or lower than normal.

No Rocking or Tipping Under Load

Wide base for stability

A scale is only useful if it stays put under weight. The wide base keeps the scale planted as the coupler comes down, helping prevent rocking or shifting that can affect the reading or make the setup feel unstable.

Protected When You're Done Using It

Case included to protect the scale

When the job is finished, the scale stores in its weather-tight hard plastic case. It keeps everything protected and easy to grab the next time you want to check tongue weight before a trip.

Got to try this out on Christmas Day, worked great and easy to use!! Tongue weighted 1620 pounds.Also, came across n a nice case which was an unexpected bonus!!

by:

The customer service and delivery are outstanding. The product exceeds expected. Thank you.



by:

the scale worked great, with easy to read the numbers i dont have to guess at the tongue weight anymore, i double tow and its crucial to have the right amount of tongue weight for safe towing



by:

Load cell should be longer
The receiver
tends to extend past the cell and come to rest on the steel below the cell and not record the tongue weight.



by:

Good tool when you have multiple trailers and different loads to check.



by:

Works great, I was unpleasantly surprised at how low my tongue weight was. Had to make adjustments to reach 10% on the tour ge. I consider 10% to be the minimum I like to tow on the tongue. Everyone who tows a trailer should use a tongue scale.



by:

This scale is GREAT, I finally got to use it while moving several trailers on our lot. I especially like the molded case to protect the scale while not in use. Since it can weight up to 4000 pounds, I am already thinking about how to check the pin weight on my 5th wheel.



by:

Works as advertised. Even came with batteries! Ready to go out of the box.



by:

Great product. Very easy to setup and use.Takes the guess work out of tongue weight for safer towing.

  • Maximum Tongue Weight for B&W Digital Tongue Weight Scale
    Hey Eric! There has definitely been some confusion around the specs on this scale. I just contacted B&W and can confirm that the B&W Digital Tongue Weight Scale w/ LED Screen # BW34KR has a max capacity of 4,000 lbs. It has been listed on our site for almost a year while we waited for B&W to release it so information has slowly trickled in and changed over time.

  • Weight Distribution Hitch for 2026 Chevy Silverado 3500 Towing Brinkley Z Air 297
    Hey Michael! When you're choosing a weight distribution hitch the most important factor is the tongue weight of the trailer. It looks like the dry/unloaded tongue weight of a Brinkley Z Air 297 is 924 lbs. Once you add batteries and propane you will be up over 1,000 lbs before anything else is loaded in the trailer. Tongue weight is typically 10-15% of the loaded trailer weight. Looking at the GVWR of 13,495 lbs that could potentially get as high as 2,000 lbs but I expect you to be more...

  • Is Weight Distribution Needed for 2019 Chevy Silverado 1500 Towing 2019 Keystone Hideout 22RBWE
    Hey Rex! Those are some great questions. A weight distribution hitch (WDH) isn't always needed but in your case you will want one. Typically if the weight of your trailer is more than 50% of the weight of your vehicle it is a good idea to use a WDH. If you are getting a lot of rear sag, trailer sway, or find it hard to stop or steer those are also good reasons to use one. I'm assuming based on that engine you have a 2019 Silverado 1500. The GVWR of your Keystone Hideout is 7,600 lbs so...

  • Correct Blue Ox SwayPro for Trailer with 1,330 lb Dry Tongue Weight
    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 tanks and the size of the batteries. Add in whatever you store in the front pass through, inside the trailer toward the font, anything you're carrying behind the rear axle on your tow vehicle, and you can easily exceed 1,500 lbs. Since you already...

  • Is B&W Digital Tongue Weight Scale Compatible With 5th Wheel and Gooseneck Trailers
    Hi Norm; the B&W Digital Tongue Weight Scale # BW34KR is designed for bumper pull trailers only. The coupler will fit onto the scale to measure tongue weight. There is no way to safely hook up a 5th wheel or gooseneck to the scale and measure. The best way to measure pin weight on these trailers is to use a commercial scale.

  • Recommended Tongue Weight Scale for a 22" Tall Coupler Height
    Welcome back Jim! The 1,000 lbs Tongue Weight Scale item # BTBRV004 is going to be the correct Big Truck Big RV scale for your 4,000ish lbs 2025 Casita 17' Spirit Deluxe trailer. You could also go with the item # BTBRV99FR which is the same 1,000 lbs tongue weight scale it just includes a snap pad. The issue with both of these is you're going to need to use some kind of lifting block because they are not adjustable. Even with the snap pad installed you're still going to be over 3" short...

  • B and W Tongue Weight Scale Recommendation for 2024 Airstream GT
    Hey Michael, this is a great question but you can use a tongue weight scale like the B and W part # BW34KR with a lighter tongue weight like what you have (relative to it's 4k capacity) and it will still work great. We had the chance to demo this jack here just last week and the trailer we used it on had only about 175 lbs of tongue weight and this still worked great. Are you wanting a scale to help with picking out/setting up a weight distribution system?

  • Best Tongue Weight Scale For 2019 27' Airstream International
    Hey Matthew, thanks for reaching out. For that setup, the B&W Digital Tongue Weight Scale # BW34KR is the best option. It can adjust to a height between 19-1/2" and 27" so perfect for a 21" coupler height. The Big Truck Big RV Tongue Weight Scale # BTBRV27FR might be a hair too short for that. I also like the digital display on the B&W scale, and the fact that is goes by 5 lb increments. That will give you a much more accurate reading versus trying to eyeball the needle on a gauge. The...

  • Will the B&W Digital Tongue Weight Scale w/ LED Screen Work with the McHitch?
    Hello Tom, Thanks for writing in. You are correct. I would not recommend using the B&W Digital Tongue Weight Scale # BW34KR with a McHitch coupler. The McHitch uses a different coupling design than a standard ball coupler, and I cannot confirm that it can sit securely on the scale. I attached an image of the scale in use with a standard coupler so you can visualize what I am talking about. A good alternative is to take your setup to a CAT scale. First weigh the tow vehicle by itself,...

  • What is Max Trailer Weight for 2017 Volkswagen Touareg
    Hey Laurie, as long as you are under the max towing capacity numbers you listed when the trailer is fully loaded you are totally safe. But since typically trailer tongue weight is 10 percent of the trailer total weight you most likely would want to try and stay under 6,000 lb for the total trailer weight since that would give you a tongue weight of right at 600 lb like what you'd need. Do you have everything you need to tow already?

  • How Accurate is the 1,000 lb BTBRV Tongue Weight Scale
    Hi Alex; the gauge on the Big Truck Big RV Tongue Weight Scale for Trailers # BTBRV004 has a +/- 5% full scale accuracy and displays weight in 20-lb increments up to 1,000 lbs. We also have it available with a SnapPad # BTBRV99FR. If you want something that is really easy to read you might also be interested in the B&W Digital Tongue Weight Scale # BW34KR. What will you be using the scale for?

  • What Are The Dimensions On The B And W Tongue Weight Scale BW34KR?
    Hey Jeff, The specs you are looking for on that B & W tongue weight scale, # BW34KR, are below. Since this is a brand new item from B & W there is no earlier date to get this yet as it is set to release fall of 2025. The over all capacity of this scale is 4,000lbs, with a height adjustment range of 19-1/2" to 27". The footplate is a 5-1/4" x 8" foot. Were there any other dimensions you were looking for on this tongue weight scale?

  • How to Use B&W Digital Tongue Weight Scale
    Hi Charles; you will start by raising the jack on your trailer. Then you will lower it so the coupler sits down on the B&W Digital Tongue Weight Scale # BW34KR. This will give you the current tongue weight rating and you can load/adjust accordingly. Once you're done you will remove it and hook up to your tow vehicle. The scale works with any coupler size and has a max capacity of 4,000 lbs. What kind of trailer do you have?

  • Which Equal-i-zer WDH for Camper With 9,500 lb GVWR and 2021 Silverado Carrying Golf Cart
    Hello Glen; to find the right system we will need to know the tongue weight of your loaded setup. The best way to find this for the trailer is to use a tongue weight scale like the # BTBRV44FR or # BW34KR. Since tongue weight is typically 10-15% of the loaded trailer weight we can take a guess based on the GVWR. At 9,500 lbs you're looking at 950-1,425 lbs. More than likely it would fall in the middle so figure around 1,200 lbs max. Assuming you're running it heavy like that you're already...

    Hey Scott, we still haven't had a chance to get our hands on the upcoming B&W Digital Tongue Weight Scale # BW34KR and since it's not out yet B and W still doesn't have solid max weight numbers for it but they told us they are shooting for a max weight of 2,000 lb.

  • Explaining the Accuracy of BTBRV014
    Hey Marc! The +/-5% accuracy specification refers to the scale's measurement tolerance. On a 2,000-lb capacity scale, that works out to about +/-100 lbs. at full capacity. As you pointed out, if you were measuring a much lighter tongue weight, such as around 400 lbs., a +/-100-lb tolerance would be much more significant. That's why this type of mechanical tongue weight scale is best used as a general setup tool rather than a precision measuring instrument. It's designed to help you verify...

  • Recommended Storage Bag for a B&W Digital Tongue Weight Scale
    Hey Kim. The B&W Digital Tongue Weight Scale w/ LED Screen item # BW34KR doesn't have it's own bag but you can use the Big Truck Big RV Accessories Bag item # BTBRV002 to store it. This bag measures 17-3/4" long x 6" wide x 5-1/2" tall. It's not water proof but it is made of water-resistant fabric. So long as you don't submerge it into water it'll keep your B&W item # BW34KR safe from the elements. What kind of trailer do you have?

  • Is B and W Tongue Weight Scale Accurate Even with Lighter Weight Tongue Weights
    Hey Gary, this is a great question but the B and W Tongue Weight Scale part # BW34KR that you referenced is totally accurate from it's max down to it's minimum so the accuracy would be considered linear. We tested it on a camper that only had around 150 lb of tongue weight and we found that it worked just fine. It would work great with your trailer that probably has a tongue weight rate around 700 lbs.

  • Weight Distribution Hitch for Boat Trailer
    Hi David; you want to choose a weight distribution hitch off of the tongue weight of your trailer. The best way to do this is to measure with a scale like # BTBRV27FR or # BW34KR. If you know the weight of your trailer and boat when fully loaded, it is typically 10-15% of that weight. Once you have this number you can figure out which system is rated appropriately for your setup. I'm also guessing you have a pole tongue, so you will need an additional adapter to make it work. I recommend...

  • Digital Tongue Weight Scale That Had Adjustable Height For Taller Trailers
    Good morning Carla, height adjustability is one of the strong points here. This B&W Digital TW Scale # BW34KR adjusts from 19-1/2 inches to 27 inches in 1-1/2 inch increments, so you can match your trailer’s natural jack height instead of forcing the jack higher or lower just to get a reading. That helps keep the setup stable and the reading accurate while the coupler settles onto the scale. Do you have one trailer in particular that’s always harder to measure than the others? What type...

  • Heavy Duty Trailer Tongue Weight Scale For 2" Couplers And 2-5/16" Couplers
    Hey Dennis, this scale works well for both. The BandW Digital Tongue Weight Scale # BW34KR is rated for up to 4,000 lbs of tongue weight, which covers most campers and many heavier utility or work trailers too. That higher capacity is one of the reasons it stands out compared to smaller analog scales. This is the highest weight rating I've seen on a tongue weight scale. As long as your coupler is 2 inches or larger (such as 2-5/16"), it’ll seat properly on the scale and give you a clear...

  • Is There An Accurate And Easy To Read Digital Tongue Weight Scale Instead Of The Needle Gauge Scale
    That’s a great question, Mark. The big advantage of the BandW Digital Tongue Weight Scale # BW34KR is that it removes interpretation completely. Instead of estimating where a needle lands, you get a clear digital readout in 5-lb increments, with accuracy rated at +/- 0.5%. So, the number you see on the screen is your actual tongue weight, which is especially helpful when small load changes matter. If you’ve ever been unsure whether a dial gauge was slightly over or under, this digital...
