- Altitude operation: If you travel to high elevations, choose models with automatic altitude compensation to maintain performance and avoid manual adjustments.
- Installation and maintenance: Some units are “all-in-one” and easier to install, while others require more complex mounting. Check exhaust routing, safety clearances, and maintenance intervals.
- Safety features: Overheat protection, CO alarms, sealed fuel caps, and secure exhaust shielding are essential for in-vehicle use.
- Noise and emissions: Look for units with low-noise operation and compliance with emissions standards to minimize disruption in compact spaces.
- Durability and support: A solid warranty and responsive tech support help when on the road. Consider brands offering technical assistance and replacement parts.
