The Level Master is an all-in-one bubble level that assists you in leveling your fifth-wheel trailer or camper. When you arrive at the campsite, the Level Master helps you find a level spot to park your trailer without leaving the cab of your truck. The large level provides a visual of the side-to-side position of your trailer.

Wheel Liners Level Master Scale

After you park, the Level Master helps you balance your trailer side to side while you are operating your landing gear. Each mark on the scale indicates 1 inch of blocking. So if the bubble is 1 block away from the center of the level, then you need to raise the side of your camper by 1 inch.

An additional level is built into the larger scale and comes in handy when you are leveling your camper front to rear.

Wheel Liners Level Master Bracket on Pinbox

The included mounting bracket makes it simple to attach the Level Master to your trailer's pin box.

Video Transcript for Wheel Masters Level Master Trailer Bubble Level Review

Hi there fifth wheel owners. Today we're going to be taking a look at Wheel Masters' Level Master bubble level for fifth wheel trailers. This bubble level is designed to mount right on top of your fifth wheel so you can easily see it from inside the cab of your truck by looking out the back window. The large bubble level in the center will make it easy to determine if you're leveled from side to side, and the small level bubble here in the center is for your front to back level. This way you can get all of your leveling done with just a single bubble level located at the front of your vehicle.We're now inside the truck and you can see here we can easily see our bubble level. This is nice when we're pulling up to the campsite and we're trying to find a spot to place our fifth wheel.

We can determine how level the ground is that we're getting ready to park on. This can minimize the amount that you're going to need to level your trailer and can also help ensure that your leveling jacks are going to be long enough to get it properly leveled because the closer you are to level to begin with, the less you're going to have to compensate using your jacks.This will also help eliminate the stressful yelling back to a family member to determine if the bubble levels that you can't see are showing that it's on fairly level ground. Now you can do it yourself before any of your passengers even get out of the truck. Check it out here in our rear view mirror.Once you find your campsite and parked your trailer as level as possible, you can see here that we've got ours parked but we're still slightly unlevel. We'll go ahead and use our leveling jacks now to get it nice and centered.

This bubble level is going to be a great tool to help you finish the job. And since it's so large and easy to view, there's no doubt that we're nice and level.Our smaller level here on the top is for front to back level and while you won't be able to see this from the truck, you can use it to fine tune it once you've got your side to side level. Each line indicates one inch of blocking so you can get an idea of how unlevel you are.The liquid inside the bubble won't leak or freeze and it's clear in color so it won't fade over time. The bubble level assembly has an aluminum construction and comes with plastic brackets to mount it onto your fifth wheel. The plastic brackets are flexible to help it fit around various fifth wheels.

You can see here they're kind of flexible. They do feel a little flimsy, but this one's been on here for quite awhile and it's held up nicely.The level will fit on pin boxes between 11 and 1/8 inches wide, to 15 and 3/16 inches wide. The level is 11 inches long by two and three quarter inches wide. It comes with everything you'll need to get it mounted onto your pin box.If you compare it to your traditional smaller levels that you'll find on RVs like the one you see here, it's going to be much more difficult to see this level. It's much smaller.

The bubble is much smaller and it's a clear bubble unlike the silver one that was in our other level. This one will still work, but again, it is much harder to see. It's also only held on by adhesive. Our other one's got nice strong mounting brackets and hardware to make sure it's securely attached.One thing to keep in mind when installing your level is that you want to be working with an already level trailer. That way you'll know your level gauge is accurate when you're looking at it later. You can use a simple carpenters level to get everything nice and level on your trailer.And that completes our look at Wheel Masters' Level Master bubble level for fifth wheel trailers.

Great product. We just took a trip from Minnesota to New Mexico/Arizona and back. Made leveling the fifth wheel a breeze, done in minutes. Easy installation, just make sure you are level first. 271032

Nice level, mounts easy on the fifth wheel hitch. 938584

It was all it was advertised to be and i will be installing it this weekend 916411

- WM6780

Mounts for the goose neck need to be a little deeper on the front as they seem to be awfully close to the curved part that makes the top. Everything was received in great condition and easy to read instructions, looks wonderful! 817933

As usual, good product at a great price. This is why I continue to shop here. 783605

Fit great! 765808

This is the second set I have bought as we had them on our Wildcat when we traded it in for a Jayco. They literaly take seconds to install, are strong and work perfectly with Andersen Jack Blocks 744542

- WM6780

This is the second one of these I had. The first was previously mounted on our Wildcat 5th wheel and liked it so much I put one on our recently purchased Jayco. The only reason for dropping one star, is the cheap basically license plate bolts it comes with. I drilled 13/64" holes for them since they are self-tapping and one of the heads snapped off halfway in and I had to drill it out.......arrgghh! Admittedly it was cold out so the steel was brittle but was still aggravating. Then I got smart and went to the hardware store and got some automotive body bolts and nuts to mount it since I could get the the inside (see pic). 744541

Good Product and easy to install. Can be seen easily from cab of truck. Was at first not happy that the mount was plastic, but remembered my last one rusting because it was metal. Time will tell how the plastic holds up. Overall very pleased with product/ 520011

I decided not to install this product since the plastic hardware provided didnt seem I would continue to get accurate readings.

This think makes it really easy and quick for me to level our RV. Don't know how we did it before! 332774

- WM6780

Works great,easy install 316911

- WM6780

I read the other reviews prior to purchase so I knew I would need to make new brackets because the brackets were plastic (but I like projects). The level feels solid and would last a long time. If you are handy with metal, and have some laying around this could be a good buy, if you don’t have the time or resources, I would suggest spending a little more money on something different. 297543

- WM6780

Finally got around to mounting it and we love it! Of course not as accurate as a small bubble but gets you close enough to level using the jacks. Very happy with the company and the shipping. Thanks! 280186

  • Maximum and Minimum Span of Wheel Masters Level Master Trailer Bubble Level Mounting Bracket
    5th Airborne pin box # 5AB-E7920 fits in place of the Leland 7920 pin box which is 14 inches wide. The Wheel Masters Level # WM6780 has an adjustable bracket that will go up to 15-3/16 inches wide so it will fit!

  • Is the Plastic Bracket for the Wheel Master Level Master UV Protected
    I spoke with my contact at Wheel Masters about the Level Master, # WM6780, and the plastic bracket is UV protected. My contact also said that the engineers tell her that the bracket is unbreakable, I suppose similar to the unbreakable combs. But if you were to break it they would send you out a new one.

  • How to Determine Correct Height Setting on Demco Hijacker Autoslide
    Thank you for providing those measurements! Since your 5th wheel hitch height is 47 inches, subtracting the bed height of 39 inches gives us the 8 inches you mentioned which is technically the setting you would need to use on your Demco Hijacker Autoslide # DM8550034. This poses a problem since the HIjacker is limited to a height adjustable from 15-1/4 to 18 inches tall. If your measurements are correct, this means that in order to tow your 5th wheel trailer with your 2019 GMC Sierra...

  • Trailer Level With Fifth Wheel Pin Box Brackets
    I do have an option for you but the Camco AccuLevel Trailer Bubble Level part # CAM25563 does not come with brackets or hardware to install. I recommend Wheel Masters Level Master Trailer Bubble Level with 5th Wheel Pin Box Mounting Bracket part # WM6780. The level comes with the mounting hardware needed. I have attached a photo for your reference. If you do not want to drill into the pin box, I recommend Hopkins Never Fade Trailer Bubble Level Set part # HM08526 that is a stick on option.

  • Can Hopkins Trailer Hitch Level be Mounted on Bumper of 5th Wheel
    Sure, you can use the Hopkins Trailer Hitch Level with Cover # HM09715 on the bumper of your 5th wheel if you like, though that may not provide the best information in terms of leveling, and there is a much better option for a 5th wheel. Instead of the hitch level I recommend the Wheel Masters Level Master Trailer Bubble Level with 5th Wheel Pin Box Mounting Bracket # WM6780. The Level Master goes on top of your pin box which you can very easily see from your truck so you don't have...
