3. Noise Level

Look for models with noise-reducing technology or inverter designs that run quieter than traditional open-frame models.

4. Portability

If you’re constantly on the move, choose a compact and lightweight unit with wheels and foldable handles.

Prioritize CO detection, automatic shutoff, and overload protection to keep your RV and loved ones safe.
