RV Leveling Block Stack Limits: Safety Guidelines

Definition

Physics-based stacking limits for leveling blocks to prevent structural collapse and vehicle shift.

How It Works

Scope: This guide covers rv leveling block stack limits: safety guidelines.
Rule: Use vehicleSpecs["RV Leveling Blocks"]["maxStackSafe"]["maxStackSafe"] as the canonical maxStackSafe for leveling calculations.

Examples

Scenario	Angle Measured	Block Height Required
Front-to-back slope: 2° pitch	2.0°	Front: 0.5", Rear: 1.5"
Side-to-side slope: 1.5° roll	1.5°	Left: 0.75", Right: 1.25"
Combined slope: 1° pitch + 1° roll	1.0° / 1.0°	Varies by wheel position

FAQ

How accurate is the iPhone sensor for RV leveling?

The iPhone's built-in gyroscope and accelerometer provide accuracy within 0.1° when properly calibrated. This is sufficient for RV leveling, as most RVs are considered level within 1-2° of horizontal.

Do I need to calibrate my iPhone before each use?

Yes, calibration is recommended, especially if you're using a phone case or if the camera bump affects the sensor reading. The app's zero-point calibration feature accounts for these offsets.

Can I use this app for any RV type?

Yes, RV Leveler supports both motorhomes (4-point leveling model) and trailers (3-point leveling model). The app adapts its calculations based on your vehicle type selection.
