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 Masters 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.

Level Master adjustment screw

You can also use the smaller level and the built-in plate adjustment screw to ensure the level is properly mounted on the surface of your trailer or pin box.

A mounting bracket (WM6700BK - sold separately) 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

Today we'll be taking a look at the Wheel Masters Level Master Trailer Bubble Level, part number WN6700. The Wheel Masters Level Master is a hassle-free solution for leveling of your RV or camper on your campsite. It's got a large easy to read side to side scale, which makes it easily visible from the cab of your truck. The smaller scale on top helps with leveling your front to back. For the larger scale, each mark indicates an inch of blocking. The smaller scale, however, uses your standard 3 scale level.

The scale measures 11 inches long by 2-3/4 inches tall and it won't leak or freeze. Now that we've gone over some of the features, I'll go ahead and show you how to get it installed, but first and foremost, we need to make sure that our trailer is level front to back and side to side. Let's go ahead and do our front to back first. As you can see, our trailer is on a level and we just need to come down in the front just a little bit. What we're going to do is we're going to have a buddy go ahead and lower it down for us and I'll say when. Go ahead. A little bit more.

Let's go with that right there. Perfect. Now with our front to back level, I'm going to go ahead and take my carpenter's level and do the side to side. What I'm going to do is I'm going to lay it down on our A frame. Now as you can see, our side to side is slightly out of level. What we're going to do is we're going to go ahead and have a buddy go around and adjust our stabilizers until we get it level.

All right, just a little bit more. Perfect. Now with our camper leveled up all the way around, we can go ahead and take our new Level Master and place it where we can still see it in one of our mirrors. You can rightly place it anywhere you want, your driver's side or your passenger's side or even your rear-view mirror, because it's large enough. We're going to place it so we can see it in our driver mirror. Now the kit comes with hardware to mount it, but for today's demonstration, we're using some double sided tape.

We want to go ahead and line up our bubble here, as well as our top bubble. We're just going to bring that down just a tad more. That way we can make sure and get them both lined up at the same time. Let's go with that right there. When we do decide to permanently attach our level using our hardware, it does have the potential to inaudible 00:02:24 up against our camper. The nice thing about this is, with our front to back level on top here, we've got an adjustment so we can adjust that back level. Now with our trailer level in place, we're all set. That's going to complete our look at the Wheel Masters Level Master Trailer Bubble Level, part number WN6700. .

Ordered this product in August 2014 and finally received it in late October 2014. Since the camping season was over I didn't mount the level until May 1, 2015. The front to back adjustment does not work so I called Wheel Masters to report the problem. The person answering the phone said she would discuss the issue with the parts manager and get back to me. It is now May 20th and no word from Wheel Masters. The mechanism to adjust the front to back adjustment is very flimsy and doesn't roll up and down the bolt assembly as it should. I have used this level on other trailers in the past and it is a wonderful tool for leveling side to side from one's vehicle. 194677

Well-built part, easily visible from the cab while getting the trailer into position. I used some clear all-weather caulking material as well as the screws provided to make sure this doesn't move once installed. 682274

- WM6700

Makes leveling trailer a dream. Not made for a light weight tag along screws way to long and will go through inside wall. 606042

- WM6700

Works great. Coupled with the drive on levelers, it makes setting up easy. 596497

- WM6700

Easy to install especially with a partner to help level the camper. I installed on my 2014 Winnebago 30RE travel trailer so that I can read using the rear view mirror on my Ford Expedition. I replaced the provided screws with shorter heavier ones. 916979

-This is my second level just like the one I bought this time. The first one only lasted 2 years. The liquid leaked out of the first one. If that happens to this one I'm going to be upset. It's a great idea but I just hope it lasts. 830734

Great leveler 772512

- WM6700

Leveling is a breeze with this bubble level. I mounted this on my travel trailer so I could see the bubble level in my side rear view mirror. When pulling on the site I am able to easily position of my trailer in the most level position possible without even getting out of my truck. The bubble also has an additional end to end bubble that allows me to level the trailer using my tonge jack without ever pulling out my hand level! 100% recommended!! 771004

I've been operating construction equipment for 49 years, starting on a small dozer. Recently, I had a job making a regulation size football field. Just for the fun of it I wondered if there was a giant level vial available to put on the D6 dozer blade to see when it is level. Sure enough I found this Level Master Trailer Bubble Level and applied it to the back of the blade. It was very amazing how much better it was holding the grade, pass after pass. The dampered indication ball moves slow and smooth. Great product for this improvisation. Try it, you'll be surprised. Thanks, 642302

nice product 620068

This level lost its liquid. I sent pictures of the failure but they insisted they get the unit back. It was not worth the $20 to send it back and have it replaced, when it only cost $30! Went to a local store and replaced it. If this one fails, I only have to take it down the street to get it replaced. 602926

Installed easily, is pretty accurate when leveling my PUP. so far so good. 550852

The level is a great tool for 5th wheel owners. I would recommend it to many rv owners. 545188

- WM6700

Perfect replacement for the faded/yellowed original on my 1996 Airstream Excella. It's placed where you can see it in the side view mirror for L/R level, then there's another level that faces up for F/R level when you're un-hitching. - 492101

Replacement. Fit perfectly. Great price shipped fast. Thanks etrailer folks. 463316

Good product at reasonable price. 425126

If I could give it more than five stars I would. It makes leveling the trailer so much easier. I don't even have to get out of the truck to check and recheck. 371496

- WM6700

Products worked as advertised, excellent customer service and fast delivery. 372387

- WM6700

Well built product. Very useful speeding up leveling from the drivers seat. Very useful for one man operation. Instillation directions are weak on package but are available on line. 360634

- WM6700

this is a good unit .. but 3 issues 1, you need to remember this is opposite of you carpenters level you are used to .. ie; you need to raise the side the steel ball is on to bring ball to center , unlike a level where you raise the opposite side ... it took a few times to get accustomed to it .. 2, the small mounting screws have rusted out within the first 2 months .. do your self a favor and purchase "good" quality stainless steel screws before mounting (also before driving the screws home dab some silicone caulk onto the threads ) this will ensure a good water tight seal into your aluminum or fiberglass trailer siding. 3. the fore and aft level (front to back) is not reliable . even after many times of re-setting or calibrating. 351848

- WM6700

Received it a day ahead of time. Product is as advertised and shipped fine. Can see side to side level and blocking needed without getting out and putting my 2' level on to determine, so saves time and effort. Also don't need to open a door to put a level on the coach floor to see front to back level. Great product from Etrailer. 309747

- WM6700

Plan to mount level on a hard surface which will allow it to attach with Velcro to the fiberglass 5th wheel Scamp so it can be seen when backing into a camping spot. Recently found being not level reduces the refrigerators ability to stay cold. This will solve the problem. 303902

Placed on my 5th Wheel Scamp where I can see it when towing . It is useful every time it gets parked. Never gets a day off.

    I spoke with Hopkins about the Hopkins Never Fade RearView Trailer Level part # HM04026 and they informed me that this device should work just fine for the -30 to -40 degree temperatures that you have in Minnesota but they didn't have an exact temperature range that the level is tested in. It does however come with a 90 day warranty so if anything were to happen in this time frame you would be covered.

  • Can the Brackets of the Wheel Masters Pin Box Level Be Installed To Inside of Level Bracket
    Sounds like you are asking if the brackets part # WM6700BK could be mounted with the portion that attaches to the pin box to the inside of the level part # WM6700. Basically you would just need to switch the left and right mounts so that the portion of the bracket that attaches to the pin box could then be then narrower than the actual level.
