Some of the most beautiful campgrounds require you to park on uneven terrain. But, leaving your RV on an incline or unstable surface means your camper will be tipping and wiggling every time you take a step.
RV leveling blocks work well for motorhomes with four wheels on the ground, but travel trailers and 5th wheels require a different type of stabilizer.
In this article, we’re going to discuss the various types of RV stabilizers and the best ones to use for your camper.

Why Do You Need An RV Stabilizer?
Stabilizers are primarily used for towable travel trailers and 5th wheels. They are designed to prevent movement once you’ve parked your camper. Nobody wants to spend time in an RV that rocks back and forth or feels like it’s sinking into the ground. It’s difficult to relax in an RV that’s not level.
Not only is it uncomfortable, but your RV can become damaged if it sits off-balance for too long. Uneven weight distribution increases the risk of tire damage. Unfortunately, tire damage is a leading cause of RV accidents, so you want to avoid weight imbalances when parking.
Finally, if you own an absorption refrigerator, having a properly leveled RV is paramount. These types of refrigerators are not designed to operate at an angle. The chemicals inside need to stay level for proper absorption or you risk damaging your fridge.
Stabilizers vs Leveling Blocks
Stabilizers are similar to leveling blocks but they have different functions. Leveling blocks are designed to level your camper. Stabilizers are designed to reduce sway, they are not built to lift the entire weight of your camper.
You should use stabilizers in conjunction with leveling blocks.
Wheel chocks and x-chock stabilizers are also effective in helping to keep your camper level. These are particularly useful if you have a set of dual tires, or if you’re parking on a steep incline.

How Many Stabilizers Do You Need?
The number of stabilizers you need depends on the type of vehicle you own. Most travel trailers require at least four stabilizers.
Fifth-wheel trailers have a unique weight distribution. They typically need more stabilizers near the rear than the front.
Ultimately, it comes down to weight. You should know the Gross Vehicle Weight Rating for your vehicle. That’s the maximum weight the RV can safely carry. It includes passengers, equipment, fuel, and everything else.
While it’s unlikely you’ll drive anywhere with your RV loaded to maximum capacity, it’s a useful number to use when buying stabilizers. Check the stabilizer capacity and use stabilizers that far exceed your vehicle’s weight limit.
Types of Stabilizers
There are four main types of RV stabilizer jacks: tripods, scissors, SteadyFast systems, and universal stabilizers. Each of them is designed a little differently and they each have their own advantages.
Tripods have three feet that touch the ground with a single point of contact for underneath the vehicle. They’re fairly easy and fast to install, requiring no special tools. Tripod stabilizers effectively protect against side-to-side movements, but they’re not ideal for stopping bouncing movements.
Scissor stabilizers look similar to trailer jacks. They use a crank handle to rise from the ground to the base of your RV. These are easy to assemble and particularly good at preventing bouncing movements.
Although they look like a jack, scissor stabilizers should never be used to jack a trailer. They are designed for side-to-side stabilization, not to hold the entire weight capacity of a camper.
SteadyFast is a brand that makes stabilizers for 5th wheels and travel trailers. These stabilizers are permanently installed so you only have to attach them once and they can be tightened to level your camper in under 45 seconds.
These stabilizers offer excellent protection against both side-to-side movement and bouncing. They are some of the most effective stabilizers you can buy, but they’re also the most expensive.
Universal stabilizers are a catch-all term to describe the stabilizers that come pre-attached to a camper. Often times if you purchase a new RV they will come with universal stabilizers included. These may or may not be sufficient to fully secure the camper depending on how much weight you put in it and the type of terrain you park it on.
You can purchase replacement stabilizers that are easy to mount and crank down into place. These generally don’t have the highest lift capacity, but they do a good job of minimizing sway.
How to Use an RV Stabilizer
Most types of travel trailer stabilizers are either portable or permanent. You place a portable stabilizer underneath the vehicle and crank it up to the appropriate height when parked. Later, you can manually remove them and store it in an exterior compartment of the RV. Permanent stabilizers are welded or drilled to the underside of the trailer. You can fold them down when needed then fold them back up underneath the camper for driving.
It’s important to note that stabilizers aren’t designed to level your camper. Instead, they’re designed to keep your trailer from swaying and bouncing. You always want to park on as level of a surface as possible. You can’t park on a steep incline and expect stabilizers to level your vehicle. For that, you need leveling blocks or wheel chocks.
Features to Look For:
After you choose which type of stabilizer you want, there are a few features to pay special attention to before purchasing.
Most stabilizers will have a lifting capacity and a standing capacity. As mentioned a few times before, stabilizers are not designed to lift your camper, they just apply pressure to keep it from wiggling. But it is a good idea to keep in mind how much your fully loaded trailer weighs.
Campers often underestimate this number. You need to account for all items and people inside the trailer, plus any supplies you may pick up during your travels. Generally, you want to estimate on the high side.
Scissor style stabilizers are special because the rated weight capacity is effective only after the stabilizer has been extended beyond a certain length. The weight capacity reduces as the scissors are lowered, so you need to read the owner’s manual to make sure you’re setting them up correctly.
The materials a stabilizer is built with makes a big difference in strength and durability. Choose heavy-duty materials such as stainless steel, metal, or aircraft-grade aluminum.
Since your camper will be sitting outside, make sure it has a powder-coated or weather-resistant finish.
Installation And Storage
If the stabilizers will remain permanently attached to your vehicle, installation isn’t a huge deal because you only have to do it once. However, if the stabilizers are portable, you want to make sure they’re easy to set up and takedown. Additionally, there should be enough storage space in your camper for the stabilizers while you travel.
Most people choose to keep their campground stabilizers stored in the exterior compartments of the RV. Scissor style stabilizers tend to take up less space than tripods.
There are a number of reasons to use pads with your stabilizers or jack stands. For one, it can protect the asphalt or concrete that you’re parking your camper on.
But more importantly, a pad will increase your stabilizer footprint so it won’t sink into soft grass or mushy ground. A stabilizer that sinks is going to be ineffective and after a few hours you’ll end up with a rocking camper all over again.
