Leveling Apps/Devices/Bubbles/Wheelbase Length
I am trying out an app for leveling.  I need to know the wheelbase for a 2007 MidBath.  I looked in reference section.  My LD is in storage and the manuals are there too. If this app looks good I will take screen shots and report back.  It is a Truma app.

Edit
Also need the track of the rear axle.

John, I have the spec sheets for 2005. It shows the 26.5" models with a 176" wheelbase.  I doubt it changed in 2007.

If this works it will tell you how many inches out of level each corner is.  That will make it much easier to set up the leveling blocks.

176", as far as I know. The wheel base for the 23.5'-24' is 158", for the 30'/31', it's 211"; this is due to the 176" frame being cut and "stretched".

I thought I measured ours at 191". If the answer doesn't come in I'll run over and remeasure.
Ours is much older though.
I stand corrected,ours measures 176" sorry for the misinformation..

The Truma app is for the company's heaters but hurried in the app for the heater is a level app.  The app is free.  The youtube video link below is the only video I could see for how I would use the app.

I claim no expertise on this matter.  Just a LD guy attempting to provide some guidance and curiosity.  

If you really, really want to do this, this was my experience.   

1. Download the ""Truma" App from the App Store

2. Open the App and click on "Tools"

3. Select "Leveling"  * a note here - you can also select "Sun Alignment" to optimize your solar panels.

4. After selecting "Leveling" you must choose Travel Trailer or Motorhome.

5. If you have chosen one of the above, you now "Lay down mobile device on any flat surface in your vehicle, with the HOME Button facing the rear of the Motor Home or Trailer.  This is a necessary step to Calibrate the measurement.

6. On the Leveling page at the top of the screen shows "distances"  This is for the Axis distance between wheels (front and back) and on the rear distance between tires side to side.  On my 2010 Rear Bath the Axis appears to be 176 inches, and the distance between rear wheels (side to side) is 77.7 inches.

7. Here's where it gets tricky and not particularity user friendly.  You must convert inches to center meters.

8. I have done this by searching help on my device (converting inches into center meters)

9. The easy way to convert inches to CM is just multiply inches by 2.54 and that = center meters CM.

10.  So if the distance from front axle to rear axle on my rig is 176 inches X (times) 2.54 that equals 447.04 CM - and the rear tire width is 77.7 X (times) 2.54 that equals 197.358 - these are the numbers  that I will enter in the Leveling input.

11. Axis (axel) distance in cm on my rig - 447.04 & Rear tire Track width 197.36.

12. Then you Click on "Accept Input"

13. The picture on your device will show a "BALL"  which you should have to center on your device to level your vehicle.

14. This is an extreme example but:

If the Ball on the Leveling Photo is in the rear of the vehicle, it means that the front is too high, and or rear too low.  You will see a CM number on each side of ALL wheels.  Front and Back.  This is number of CM that you are out of Level.  So if my device photo shows the Ball in the Rear, and the CM number is 17.4  you would divide 17.4 by 2.54 and that would tell you that your vehicle is 6.8 inches low in the rear. WHEW!

Why would anyone want to go through this much trouble?  Now you truly know that I have too much time on my hands!

We use a 2' carpenter's level and it works every time, but I can see that this could be useful.  It also appears to work without WIFI.

Most respectfully,
Tony R (aka codefour)

For step 7, you do not have to make any manual conversion, there is setting where you can set the units ....

i am still waiting for motorhome delivery and it will take some time after delivery and hydraulic leveler installation and I thought I would get levelmate Amazon.com: LogicBlue Technology LevelMatePRO+ Wireless Vehicle Leveling... to have some help before automatic levelers installation. This app, if work, will save around $170 ...

Hi Tony and Muhammad, I can save you lots more money!   Get these bubble levels, they come in a package of six. Save a few for RV friends.  I keep one in my refrigerator. 6x Spirit Bubble Levels, Precision Circular Level Mult-Directional Leveling...
   Above the driver on the edge of the cabover platform I have a level for side-to-side, and just to the left is one for front-to-back.
 They are low tech, but more than acurrate enough to know if you are level. I did mount them to a flat aluminum plate to make them easy to attach. And the screw on the right is in a larger hole to allow calibration. A little glue keeps it aligned. Cost about $10 for both.    RonB

We used the levels for years and I was completely happy. The kids bought me a Level Mate Pro it communicates with my phone and it actually works pretty good. It'll show which wheel and how much, I double check with my levels. If you need an app based level this works pretty good.

I've seen various leveling aids offered over the years, but wasn't impressed by any of them. Until now, I got along fine with a couple of bubble levels in the cab. But I recently inherited a LevelMate Pro setup, and I have to say that I've come to really like it.

In a nutshell, its iOS app (Android also available) tells me exactly how many inches off level I am at each wheel, so I know how many Lynx leveling blocks I need. How does it do this using just one small sensor box mounted on a vertical wall? Determining the angle is easy; almost any smartphone can do that, and there are plenty of apps (for example, Apple's Measure) that can tell you how many degrees off you are. But when setting up the LevelMate app, you tell it your rig's exact width and wheelbase, and from that it can calculate how many inches off level you are at each wheel. It can show either front + side or top views; I usually use the front + side view (see attached screenshots).

Using this system has made my campsite setups a lot faster and easier. Now, is LevelPro worth its $145-$180 cost? (There's a LevelPro+ version that I haven't looked at.) Is it really thirty to fifty times better than a pair of $3 bubble levels? Probably not. But then, we could all have saved money by buying Fleetwoods instead of Lazy Dazes. ;-) I won't tell anybody this is a "must"... but I have found it to be a nice convenience.

I thought free app info posted by op shows how many blocks I need to put under each tire just like $170 tool. What am I seeing here?
As for bubble levelers I can have them free as phone app as well but they will not tell be number of blocks under each wheel.

I feel a bit out of the times having only used a set of bubble levels over the last two decades.

The bubble levels do require using the on-board computer (my brain) to determine which wheel(s) need lifting, so far it has worked fine.

One level is mounted on the dash, the other on the driver's door, easily observed from the driver's seat. After using the levels a few times, the 'computer' is able to determine which wheels need blocks to be level.
Unfortunately, this system doesn't work well with blue-tooth.

I opted for the upgraded low-tech option.  the tic-marks approximate the number of lynx leveler blocks needed.
Some greyware still needed to get it exact.

Do the numerical markings on this Hopkins device  (0 - 7) represent inches, or it just a reference number to try to use as a guide?

Not exactly a "gotcha", but to get accurate readings from the stick-on levels, the RV needs to be level before sticking them on. I am going to change the stick-ons that I have now to the larger Hopkins with the graduated markings, and will do the same procedure that I did when I stuck the little ones on the dash and the door years ago, i.e., take the rig to a level-as-possible parking lot, and use 24" carpenter's levels and Lynx blocks to get the rig level, front to back, side to side, then stick on the levels. This involves finding a parking lot, a less-jammed time, and a lot of hopping in and out of the truck, so I am not looking forward to doing it; it's an easier job with two people.

Note: The TK is a bit "raked", anyway; it sits slightly lower in the front than in the back.

YMMV, as always.

Joan, how do you account for the rake in your TK when placing the levels?

I think they are calibrated in AMU (Angular Mythical Units)  and are more reference than Lynxes (aka 1 -1.5 in).
Since I have been homebound since March,  I'm afraid I'll have to recalibrate my brain to relearn the Kentucky windage.
I find I am more exacting the longer the stay.  If just overnight, I am less concerned with perfectly level. If it's a short stay in inclement weather, I have occasionally put the rig in TOTR (Turn Off The Reefer) mode.
