RV Leveling, Chocking and Stabilizing
Separate leveling, wheel chocking and stabilizing with two original diagrams, practical setup decisions and the manufacturer-specific differences that matter.
The RV Dummies editorial team · Published
Before you turn a crank or press a leveling button, know which job you are doing. Leveling corrects the RV’s tilt. Wheel chocks restrain rolling. Stabilizers reduce the movement you feel when someone walks through the trailer. Asking a stabilizer to fix a low corner can turn a slightly crooked campsite into damaged equipment.
Start with a workable parking position, then use the equipment your RV actually has. A travel trailer with a tongue jack and four stabilizers needs a different routine from a fifth wheel with automatic leveling or a motorhome with air suspension. Here is how to build a calm, repeatable setup without treating every jack as interchangeable.
First, identify what is under your rig
Find the names and model numbers on your jack controls and in the RV’s equipment packet. You are looking for words such as stabilizer, landing gear, tongue jack or leveling system. An electric switch does not prove that the equipment can level the RV. Some powered assemblies only steady it once it is already level.
For a conventional travel trailer, wheel supports make the side-to-side correction and the tongue jack adjusts the front-to-back position. The corner stabilizers have a separate job. A fifth wheel’s front landing gear supports the front during the approved unhitching process; other installed jacks may level, stabilize, or do both as part of a coordinated system.
Write the RV model, system name and manual page on a small setup card. Include which control stops movement. That gives a second adult useful information if the usual setup person is busy, and it prevents a neighboring rig’s familiar-looking panel from becoming your instruction manual.

Choose the ground before choosing the blocks
Walk the space before committing to your final parking position. Check the whole rig: tire locations, jack landing spots, slide clearance, door and step space, and the reach of your hookups. A few feet of repositioning may solve a problem that would otherwise follow you through the rest of setup.
Look closely at where each foot or support will land. A surface that carries a tire may behave differently under a small jack foot. Grass, sand and hot asphalt deserve particular attention. Use suitable load-spreading pads where your equipment instructions call for them, but do not assume a bigger pad makes saturated or unstable ground acceptable.
For example, if the only position with room for your slide puts a rear jack beside a washed-out edge, ask for another position or campsite. Avoid building an improvised tower to preserve the view. Blocks, ramps and pads have their own load, placement and height limits; those limits belong on the decision list before you start.

A conventional travel trailer: side-to-side before unhitching
If your trailer uses wheel blocks or ramps rather than an automatic leveling system, make the side-to-side adjustment while it is still attached to the tow vehicle. Check level at the location recommended for your RV. Identify the low side, position compatible supports as their instructions require, and move onto them slowly with everyone clear of the tires and the rig’s path.
Check again before disconnecting. The goal is a properly supported, usable position, not a rushed attempt to land somewhere near the blocks. Supports must suit the tire size and load; do not leave a tire precariously hanging over an edge. If the position is wrong, make a deliberate reset with the tow vehicle rather than trying to push blocks under a loaded tire.
Secure the trailer wheels with suitable chocks before unhitching. Follow your hitch’s actual release procedure, then use the tongue jack for the front-to-back adjustment. A fifth wheel has its own landing-gear and hitch sequence. Do not substitute these travel-trailer steps for that procedure, and do not remove the chocks just because the jacks are down.

Let the stabilizers steady the trailer
Once you reach the stabilizing step in your RV’s setup order, bring the stabilizer feet into contact as their instructions specify. Airstream describes its stabilizers as making snug contact to reduce movement, not lifting the trailer into level. More cranking is not automatically more stability.
If a door suddenly becomes hard to close as you load a stabilizer, stop rather than using the other corners to chase the problem. Uneven stabilizer pressure can distort the setup; Winnebago warns that it can contribute to door or slide binding. Check the correct procedure and the support underneath each foot before continuing.
Some motion can still be noticeable when people move around. Do not try to eliminate every bounce by transferring the trailer’s weight onto stabilizers. If the movement seems excessive, investigate the setup or seek service advice instead of tightening until something gives.

Automatic leveling still needs a prepared campsite
For an automatic system, use the operating sequence for that exact installation. Check the required power supply, parking-brake and transmission conditions, and where people should be during the cycle. Keep everyone clear of moving equipment and avoid walking around inside while the system is finding level.
Even the ignition setting is not universal. Lippert’s motorized unidirectional system manual calls for a running engine during its automatic procedure. The Equalizer manual linked below describes an installation that extends with the ignition off. Copying one instruction into a checklist for every motorhome would create an avoidable mistake.
On a fifth wheel, follow the system’s instructions for chocking, supporting the front, unhitching and moving the truck clear before starting automatic leveling. Do not begin a cycle merely because the button is available. Lippert’s Ground Control manual also distinguishes its middle stabilizing jacks from the jacks doing the leveling work.
If the display reports an excessive angle or a jack reaching its travel limit, follow the fault instructions and reassess the parking position. Repeatedly pressing the same button does not give a jack more usable travel. A flatter spot is often the right solution.

Put slide order on your own checklist
Check your RV’s required slide order. Winnebago’s 2026 towables instructions require leveling and stabilization before slide operation. Jayco’s 2026 family-towable setup sequence places slide extension before lowering the stabilizers. Those are already two different sequences among towables.
Motorhomes can add another distinction. The 2026 Newmar Ventana guide describes checking slide clearance with the coach at ride height, extending when conditions are appropriate, then dumping suspension air and deploying leveling jacks. It also explains what to do when slide clearance is insufficient. That is a model-specific procedure, not permission to extend every RV’s slides on an uneven site.
Record the order for your RV, including interior and exterior clearance checks. If its instructions seem inconsistent with an installed component’s manual, get the manufacturer or qualified service team to resolve the conflict before operating it.

Know when to stop and reassess
Stop if a pad sinks or slips, the rig shifts, a jack bends, or a tire begins to lose its support. Keep people away while you work out the next step. Follow the manufacturer’s safe stopping and recovery instructions; do not reach underneath to rearrange a pad while the equipment is loaded or moving.
Treat a visible hydraulic leak as a service problem, not something to locate with your fingers. High-pressure fluid can penetrate skin. Do not bypass a warning, force a stalled mechanism or repeatedly reset the system without addressing the cause.
Leveling equipment is not a substitute for properly rated service supports. The Lippert and Equalizer manuals cited here prohibit using their systems for tire changes or supporting under-RV work. Their warnings also prohibit leveling with the wheels lifted clear. If you cannot get a stable, compliant setup, reposition using the approved procedure or get qualified help. Never crawl under the RV to prove that it is secure.

Recheck when the campsite changes
Take a final look after the approved setup sequence is complete. Confirm that the feet are seated, supports have not shifted and the rig is level where it needs to be. A level bubble is one part of the check; it does not tell you whether a foot is sinking into the ground.
Reassess after heavy rain or a noticeable change in how the trailer feels. For example, if a conventional trailer settles toward one side overnight, the stabilizer on that side is not a convenient lifting jack. Keep people clear and plan a proper correction using the RV’s procedure, which may mean preparing to rehitch and reposition. If the ground is failing, getting another site is more useful than repeatedly adjusting the same unstable setup.

Make a card that answers the next question
A useful setup card should tell you what to do next without making you reread a full manual at the campsite. Keep the full instructions available, then write a short version for your own equipment. Start with the parking decision and finish with a visible check of the completed setup.
Include these fields: RV and leveling-system model; where to measure level; approved wheel supports and pads; when to install chocks; the hitch-release steps; the required brake, ignition and power settings; slide and stabilizer order; how to stop the system; and what a travel-limit warning requires you to do. Leave a field blank until you have verified it rather than filling it from memory.
Make a separate departure side. Keep a towable secured against rolling throughout rehitching, retract equipment in its approved order, and visually confirm every jack is stowed before moving. Account for pads, blocks and chocks during the final walkaround. One person can read the card while the other confirms the action; neither needs to guess what the other already finished.
The payoff is a routine you can repeat when you arrive tired or someone is waiting behind you. Pick a workable site, give each piece of equipment its intended job, and stop when the setup stops making sense. Camp will still be there after you take the extra minute.
