RV Leveling Systems: What You Need To Know

rv-leveling-systemsEvery RV requires a leveling system for 2 reasons:

  1. To meet the requirements of the refrigerator. If it’s not level, it will not function very well.
  2. For the comfort of the occupants. Sleeping with your head in a downward slope can be uncomfortable. Likewise, rolling out of bed is a real possibility if you’re parked with one side higher than the other.

The key question for the new RVer is, “What type of leveling system do you have for your RV?”

Here’s what you need to know about RV leveling systems…

 

Simplest RV Leveling Option

wood-planks-for-rv-leveling

Slide-in pickup campers, some soft-sided tent trailers, teardrop trailers, and other lightweight RVs aren’t likely to have factory-mounted RV leveling jacks of any sort.

Usually, 2×6 planks are used to accommodate the relatively minor adjustments required to level out such a unit.

As a precaution, at least one wheel that isn’t on a leveling plank should be blocked in order to prevent the RV from rolling off the leveling block.

Many RVers upgrade to a  stackable set of plastic RV leveling blocks that are cleaner and much lighter in weight. Designed to snap together, you can build a ramp of sorts from your block kit to gain the proper height for leveling your RV.

 

RV Leveling Jacks

Most mid-sized RV trailers (travel trailers and 5th wheel trailers) come with stabilizer jacks attached at the corners of the RV. You crank them down by hand until you have some of the weight of the trailer applied to the jack.

NOTE: These jacks are only designed to level out an RV, not to lift the trailer off the ground as would be required to change a tire.

Stabilizer jacks require both care and maintenance. If you accidentally  attempt to pull away while your RV is leveled with these jacks they will very easily fold over and be destroyed. They must be retracted completely, because even very light impact will tear them clean off your RV.

Crank-up jacks must be kept clean and greased. Hanging down below your RV, they will quickly collect dirt and grit when you travel on gravel roads. That will ultimately hamper the ability to turn the long threaded rod that makes the jack raise and lower.

A common accessory to assist in raising and lowering screw type jacks is a cordless electric drill. Used to quickly raise or lower the jack, a drill with a socket can save both time and effort!

 

Hydraulic RV Leveling Systems

Many motorhomes come equipped with hydraulic leveling systems.

With a group of 4 buttons near the driver’s seat, you can level up your RV in total comfort.

Even these seemingly foolproof RV leveling systems require some attention though. Maintenance is usually limited to making sure the hydraulic reservoir has sufficient fluid, but there are some concerns to be aware of when using hydraulic stabilizer jacks:

  • Hydraulic jacks are much stronger than manual screw jacks. Using them together, you can easily raise the entire motorhome off the ground. This is very helpful when the time comes to change a tire — because crawling under a motorhome can be difficult with a flat tire.
  • When using the hydraulic levelers, always lift either one complete side or one complete end of the RV. This will help you avoid twisting the unit which may cause damage to the structure.
  • Where you use your hydraulic levelers is also a concern. A concrete surface is best, but blacktop can be used with caution. If ambient temperatures are high, you will likely create a depression in the blacktop with the weight of your motorhome concentrated on the relatively small pads of your leveling jacks.
  • Attempting to use a hydraulic leveling system on a soft dirt surface will prove futile, as the jack will just sink into the ground. Be sure you have a solid footing when you use this type of RV leveling system.

 

Here are some small RV levels that adhere to the 4 corners of your RV and enable you to see how level your RV really is.

Fun From Around the Web

  • not a happy camper!

    We purchased a 2005 Rockwood, 31 ft with two slide outs travel trailer. We used it for the second time this week-end. Everything has worked great until we got ready to pack up to leave. Our son was bringing in the bunkhouse slideout, when 1/2 way in, it stopped. We then tried to bring in the sofa/dining area, and it wouldn’t budge. We have tested all fuses, battery connections, power, etc. and everything else is working and showing proper voltage and charge. We were told that you could manually put the slideouts in, but nothing in the manual explains that, nor do we see any type of mechanism that indicates you can do that. Needless to say, we had to leave our camper at the campsite. Any suggestions? Thank you!

      Not a Happy Camper, I’m guessing this is your first RV with slideouts. I say that because sometimes when one is unfamiliar with things they get a bit frazzled when it doesn’t work and might over look something simple in their confusion. Manual systems usually consist of a hand crank that you install through a hole in the sidewall that will let you crank in the slideout. Other setups include using a socket wrench at the electric motor inside the RV to retract them. It’s unlikely that both slideouts have experienced a mechanical problem so I’d recheck that you haven’t missed a circuit breaker of fuse.

    Thanks for your previous help on partially extending slide outs and the warning about rain. Now, can help in another area ?
    I Park my class A Tiffin Phaeton, 2009 year, in the street next to my home. Even with the step button turned off, and the engine off, if I open my entry door, the step will deploy and partly extend about 4-5 inches & stops, hitting the street curb. The step motor stops, is not warm to touch, no sound is heard that would warn me that the motor is binding up. When I do engage the ignition key, even without starting the engine, the step comes to full retract, no problem. I can’t position the coach to allow full step extension since I would endanger a traffic collision to my coach by so doing. I was told by at least 7-8 repair facilities that this causes no harm to the gears or motor. However, Kwikee Step contends that this could damage the motor. They have had lawsuits about step deployment so I believe their answer is to cover their rear ends. Again, the step button will not lock up the step into full retraction. Opening the entry door automatically causes the step to extend. Curtis, do you have any advise on this problem ?

    • Curtis

      irv kodimer, Most motorhomes that I’m familiar with will leave the steps fully retracted if you turn off the house and chassis batteries before you open the door. That way you can jump down and leave as a last step after closing things up for a period of storage. It also helps to remind you to shut off all the batteries as the last step before you walk away.

    very green just got ggb2 cant find out where water is coming from millde floor just 4 jns from tiotit if water or pump on if off dosen t sorry rv ggb 85 both have to be off it just keeps on coming like something is off and pushing it out but it just mets in middle then goes in to carpet tks leslie

      Louis St Andrew, Sorry but I can’t decipher your short hand. Please resend with complete words and sentences and maybe I can be of assistance.

  • jpfx

    hello Curtis, can I ask if it might damage a hydraulic leveling system to use it when the vehicle sits in the drive for a few months? thanks

    • Curtis

      jpfx, It won’t hurt a thing to leave your RV on the jacks for a few months. Over time only 2 things can happen. The hydraulic cylinder may leak down some. Usually this amounts to the cylinder just settling a bit as the oil is seeping around the piston inside the cylinder so you don’t see any leakage. Run the cylinder back out if it settles and your good to leave it again. If you’re set up ocean side you may get some rusting on the chrome cylinder rods. Coat them with a light film of grease if you think this might be an issue. Under normal circumstances you shouldn’t have to do anything.

        many thanks

  • dick hunter

    hello Curtis i have a 34ft class it has a supper slide will the hydraulics for the slide run hydraulic lifts

    • Curtis

      Dick, Possibly but without seeing it I hesitate to say. Some slideouts have a complete 12v hydraulic pump with built in reservoir that would allow you to plump additional functions. The key is the size of the reservoir. You can easily run into a situation where it won’t hold enough oil causing cavitation of the pump. That’s where it tries to pump air because you ran out of oil. That will give you spongy and erratic operation, plus cause undue wear on the pump.
