Winnebago View/Navion: Wheelbase & Block Calculation

Definition

Learn how to level your Winnebago View/Navion with precise axle and leveling block calculations.

How It Works

Scope: This guide covers winnebago view/navion: wheelbase & block calculation for US users.
Rule: Use vehicleSpecs["Winnebago View/Navion"]["2024"]["wheelbase_in"] as the canonical wheelbase in for leveling calculations.

1. Position your RV on the campsite and ensure it's in park with the parking brake engaged.
2. Open the RV Leveler app on your iPhone and select your RV type (motorhome or trailer).
3. Place your iPhone on a flat surface inside the RV and tap 'Calibrate' to set the zero point, accounting for any camera bump or case offset.
4. Measure the current angle by placing the iPhone on the floor and reading the pitch and roll values from the app's sensor display.
5. Enter your vehicle's wheelbase in the app's geometry settings. For 2024-2026 Winnebago View/Navion models, the wheelbase is 170 inches (4318 mm) (vehicleSpecs["Winnebago View/Navion"]["2024"]["wheelbase_in"]).
6. The app calculates the required block height for each wheel position based on the measured angle and your vehicle's geometry.
7. Place leveling blocks under each tire according to the calculated heights, starting with the lowest point.
8. Re-check the level using the app after placing blocks to verify you've achieved a level state (pitch and roll near 0°).

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.
