Sturdy, rustproof aluminum construction
2 Simple installation options

Specs:

Dimensions: 11" long x 2-3/4" tall
1-Year limited warranty

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.

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.

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.

Still extremely happy with our Wheel Master Level on our tow behind toy hauler. We also have truck camper that we will be using this winter for a cross country trip and I plan on buying another set for that camper. And I will definitely be ordering it from Etrailer because I can be sure I will get the product I requested packed correctly so it ends up delivered in perfect condition.

Love the huge level and the front to back level on it. Will be a time saver and keep me and my leveling person from dancing the tango.

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,

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.

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.

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!!

It’s great

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.

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.

by: Tom 08/06/2025 One Year Later

I can see the bubble using my rear view mirror. Very easy to install, and it's holding up well.

by: Victor 07/28/2021

Works as intended. Comes with cheap screws, replaced with Stainless Steel self taping. If attaching to fiberglass shell, be sure to chamfer the gelcoat so it doesn't chip and drill appropriate size pilot holes. Screws should bite into fiberglass only!

Still holding up!

by: Mike 05/22/2023

Level is great but mounting it leaves you with limited options. They want you to screw it to the camper . Not a great idea. Trying to come up with a bracket to mount to my pin system on my fifth wheel will work fine on a regular camping trailer

Depending on where you want to mount the level, there is a bracket that can be used to mount it to the 5th wheel king pin. It is part # WM6700BK on our site.

by: copperjohn 03/12/2017 One Year Later

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.

by: John C. 05/20/2015

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.

by: Ken 07/21/2015

I just installed a Level Master bubble level on my trailer to go with my Andersen levelers. Since I was not interested in drilling holes in the thin fiberglass I did it another way using 3M Extreme outdoor double sided mounting tape. First I cut out two pieces of 1/8" by 2 3/4" by 2 3/4" aluminum. I drilled and tapped 2 6x32 holes in each piece. Four very short 6x32 screws were used to secure the bubble level to the aluminum. Two strips of the tape were used on each piece of aluminum. The level was carefully mounted. That is powerful tape so you sure need to get it in the right place. There is a little adjustment room with the screws.

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. -

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

by: D2 10/22/2016

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.

by: Jeff C. 08/08/2019 One Year Later

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.

by: Eric H. 04/05/2014

Backing made of a light metal and easy to install. Easy visability when new and I don't expect that to change. Fit just fine on my pinbox. Not much more to say.

by: Sandy F. 03/19/2014

We just traded travel trailers after 17 years. I missed this thing SO much it was the first accessory I bought for the new one. This should be standard equipment on all new units.

Always great service with knowledgeable saleswoman.

by: Dale 08/07/2018 One Year Later

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

by: Tom 07/23/2018

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

Will the Hopkins Never Fade RearView Trailer Level Work In Extreme Cold
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.

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.
