RV Level How to level a caravan on a slope: side to side first, then front to back
Treat the two tilts as two jobs. Sideways tilt lifts one side, nose tilt lifts the front or rear pair, and RV Level shows both as one set of centimetres per wheel.
On a hillside pitch you rarely have only one problem. Use the app to see how much of each you have before you touch a ramp.
Side to side
A sideways tilt raises one whole side. With a 1.8 m track and a 3.0° lean to the right, the right-hand wheels need 9.4 cm each and the left ones none. Run onto a ramp on that side first.
Front to back
A pure nose-down tilt of 2.0° on a 3.5 m wheelbase asks for 12.2 cm under both front wheels and nothing at the back. The same angle on a longer wheelbase needs a taller wedge, because the front sits further from the rear.
Both at once
| Wheel | 3.5 m x 1.8 m (cm) | 4.2 m x 2.0 m (cm) |
|---|---|---|
Front left FL | 4.7 | 5.2 |
Front right FR | 0.0 | 0.0 |
Rear left RL | 20.0 | 23.6 |
Rear right RR | 15.3 | 18.3 |
The longer, wider rig needs more at the low corner for the same angle, which is the reason you type your own dimensions.
A caravan has fewer wheels than four
The calculation assumes four contact points on a rectangle: wheelbase between front and rear, track between left and right. There is no caravan mode and we do not claim it fits single-axle caravans or dual wheels. With only two wheels on the ground the distances you type are your own approximation, so treat the numbers as rough and re-read after every move.
Do it in this order
- Unhitch or park as you normally would, chock the wheels and put the phone flat on the floor.
- Open Level and look at the two biggest numbers.
- Fix the side-to-side error first. Ramp or block the low side.
- Re-read. Now deal with the front-to-back error.
- When the Level badge shows, tap Save this spot and give the pitch a name. Next year, Spots lists it with the biggest wedge, such as the front right at a given height.
The saved line is the largest wedge only, for example FR 12.2 cm, or Level if you saved on a level reading. A spot is easier to repeat when the name says which side was low.
What the angles look like at a pitch
A small tilt is bigger than it feels. A reading of 0.2° to the right and 0.1° nose-down on the default vehicle still asks for 1.2 cm at the front right and 0.6 cm under the front left, so the app does not call it level: the limit is 0.5 cm. That is why the badge means something.
Watch the colour while you work. Orange means roughly 1 to 4 cm left, red means more than that, and green means you are under 1 cm. The badge only appears after the 1.2 second hold at 0.5 cm or less.
