For many years I owned diesel pusher motorhomes before downsizing to a more modest Class C diesel. Aside from the larger amount of living space afforded by the pushers, another significant but often overlooked feature of these coaches are the hydraulic leveling systems. Although my late-model Navion has all the comforts of my previous motorhomes, I really miss the convenience and benefits provided by the levelers. Although many modern coaches of all sizes now offer hydraulic levelers available as standard or optional equipment, this is a relatively new offering on smaller units, and can be an expensive upgrade.
I recently had the opportunity to review a new product called the ReVo leveler. Although it does not provide actual leveling, for those without leveling systems in our coaches, this handy device is the next best thing. The ReVo leveler (www.revoleveler.com) quickly and accurately indicates the amount an RV is out-of-level, on which side, and by how much. It’s most useful function is that it calculates exactly how much blocking needs to be applied in order to level the vehicle.
It is important to point out that the ReVo leveler is primarily designed for towable units, due to the fact that the device takes into account both axle and jack leveling. As a motorhome owner, I was able to benefit from the ReVo, but it has more features than can be fully utilized by a motorhome.
The ReVo comes with an adhesive-backed bracket that is applied to the outside of the RV. When you wish to level the vehicle, you simply mount the ReVo on the bracket, select the desired display function, and the unit will display the amount of level correction required on each axis. The bracket need not be mounted level because any mis-alignment is corrected during the initial or subsequent calibration and setup. When it comes time to level your RV, simply mount the ReVo on the bracket, which should be mounted on the driver’s side near the front.Push the button for the desired function (front/rear, left/right) and a large red arrow will indicate which end or side of the coach needs to be raised. Both arrows will turn green when the coach is level. Although it is obvious when leveling front and rear which arrow indicates the front and which indicates the rear, it was less obvious when leveling left and right. The manufacturer could improve this by adding two more illuminated arrows pointing left and right. Despite this, the unit is easy to use, and it simply displays the number of inches that the vehicle is out of level. This can be directly translated to board or block height.
For motorhomes without hydraulic jacks, leveling involves driving up on blocks until the unit is level. Trailers are slightly different because both axle as well as jack leveling may be required. The ReVo vastly simplifies this task by providing straightforward feedback for the owner to more easily level their coach.
Note that it is not within the scope of this article to describe the operation of the ReVo leveler in detail, but there is good information on their website (www.revoleveler.com). The ReVo leveler is a vast improvement over bubble levels, and I highly recommend it for trailer owners, as it makes leveling your coach much faster and easier and eliminates the guesswork.
