The myth of the perfectly level RV campsite continues to elude campers everywhere. One ingenuous RVer stopped looking for it and instead he invented the ReVo Leveler, an after-market RV accessory that helps trailer and fifth wheel owners position their wheels without getting out of the tow vehicle.
“I developed the ReVo Leveler to fill the void between bubble levels and fully automated leveling systems on the market today,” says inventory Larry Karan on the ReVo website. His new product aims to make campsite setup faster and easier in any terrain by:
- displaying your levelness from left to right and front to back
- showing how much jack extension is needed to become level before disconnecting your tow vehicle
Karan says the ReVo doesn’t require any longer to integrate his product into your RV campsite set up routine. It only takes “about the time it currently takes you to set up your RV on a campsite, depending on your amount of experience. Level left to right, press a button. Raise your RV to a disconnect height, press a button. Level your RV front to back, press a button. Raise or lower your RV to a connect height, press a button.”
For ease of use, Karan recommends carrying leveling boards that are 1/4” and 1/8” thick “because the display will show values in tenths of an inch. It’s easy to be exact when you know what to use,” he explains.
The device nests on an adhesive-backed permanent mount when in use and removed for storage when not. It installs without any special tools and doesn’t require drilling holes in your RV. Easily visible indicator arrows are visible from the driver side mirror, “Making level left to right a one person job, without getting out of the tow vehicle,” says Karan.
The ReVo doesn’t require any wiring modifications and runs on a rechargeable battery. A 12v car charger adapter and cable are included. Care should be taken when using the product as it’s an electronic device with sensitive instruments inside that shouldn’t be kept out away from water and other harsh climate conditions.

Often called “The O.G. of full-time RVing,” Rene Agredano and her husband Jim Nelson hit the road in a fifth wheel trailer in 2007, after their dog Jerry lost a leg to terminal cancer. Sixteen years later they are still traveling and sharing their nomadic adventures at LiveWorkDream. As a self-employed wordsmith, Rene shares her expertise for many RV industry videos, publications such as the Escapees RV Club Magazine, and has authored numerous books, including the Essential RVing Guide to National Parks, and Income Anywhere, a guide to earning money on the road. She has been featured in global media outlets including the PBS documentary “NATURE: Why We Love Cats and Dogs,” The Guardian Sunday Edition, and the Dan Pink book Free Agent Nation.
Absolutely love mine. Set up the ReVo once and your done. Simple to use after that. Love the ability to recharge. With Andersen hitches leveling blocks I can level with no help. The wife and I can argue about important things, like what’s for dinner or which wine to open..
