Buying Guide
- Compatibility and adapters: Look for kits with multiple adapter sizes (1″, 1.25″, 1.4″, 1.5″, 2″) to fit your generator’s exhaust pipe. A universal fit reduces the need for custom parts.
- Vent direction and placement: Choose configurations that vent exhaust above the roofline or away from living spaces. This minimizes fumes inside the RV and reduces noise transmission.
- Material and durability: Opt for corrosion- and weather-resistant PVC or similar materials. Weather exposure is common in camping, so durability matters for long-term use.
- Weight and storage: Lightweight, compact kits with included storage bags are easier to handle and store when not in use.
- Ease of installation: Kits should offer simple, tool-light installation with clear instructions. Consider whether you need to disconnect and reattach the system frequently.
- Noise impact: Some designs offer vibration reduction and quieter operation. Rubberized straps and upward venting help minimize exhaust noise.
- Durability vs. budget: Higher-priced kits may offer longer service life and broader compatibility. Balance your budget with expected use and RV type.
- Safety considerations: Ensure the system keeps exhaust away from living spaces and does not obstruct roof ventilation or emergency exits.
