Hymer vs. Airstream: Transatlantic Design Philosophy
Definition
Comparing the European chassis approach (Hymer) with the American design (Airstream) for leveling.
How It Works
Scope: This guide covers hymer vs. airstream: transatlantic design philosophy.
Rule: Use vehicleSpecs["Hymer"]["wheelbase_in"]["wheelbase_in"] as the canonical wheelbase in for leveling calculations.
| Specification | Value | Notes |
|---|---|---|
| Wheelbase | TODO: Add wheelbase for Hymer caravan (needs official source id or JSON key) | Wheelbase for Hymer caravan |
| Wheelbase | TODO: Add wheelbase for Airstream trailer (needs official source id or JSON key) | Wheelbase for Airstream trailer |
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.Download
Get precise leveling calculations with RV Leveler. The app uses your iPhone's sensors to measure angles and calculate exact block heights for each wheel position.
