Buying Guide
Key considerations when choosing big propane tanks for an RV include capacity needs, compatibility, safety, and storage. The following questions help compare options:
- What capacity do I truly need? Consider trip length, heating needs, and cooking frequency. Higher-capacity tanks reduce refills but take more storage space.
- Are there safety certifications required where I travel? Look for DOT, Transport Canada, and OPD features to meet local regulations and ensure safe handling.
- Is cross-border use a factor? Tanks with OPD and proper labeling ease transport between the US and Canada.
- Do I need a single large tank or a dual-tank setup? Dual-tank configurations offer extended fuel without frequent changes but require more exterior space and a protective cover.
- What accessories improve usability? Gauges, gauges with built-in safety relief, hoses with proper NPT fittings, and protective covers can simplify daily use and storage.
Size and Type Considerations
Small vs. large tanks determine how long you can cook or heat before refilling. Horizontal vs. vertical tanks affect mounting and space in your RV bay. ASME-certified tanks provide stability for longer trips, while OPD-equipped tanks help prevent overfilling issues at filling stations.
Safety and Maintenance
Regular inspections for rust, valve integrity, and leak checks are essential. Use approved regulators and fittings, avoid damaged hoses, and store tanks away from heat sources or vehicles that can create pressure changes inside the storage area.
Storage and Convenience
Protective covers improve exterior aesthetics and protect cylinders from weather when parked. Ensure there is adequate clearance for airflow and safety around the storage area to reduce fire risks.
