- Noise level: Look for dB ratings in Eco or low-noise modes for night comfort on board.
- Installation complexity: Some units include full accessory kits; others may need professional help or custom fitments.
- Energy efficiency: Eco modes and refrigerants (like R-32) can extend battery life in off-grid setups.
