Buying Guide: Key Considerations for RV Tote Tank Carriers
Choosing the right carrier depends on bumper size, tank capacity, and storage needs. Consider these factors:
- Confirm bumper width and height (commonly 4″ to 4.5″). A universal fit reduces installation hassle.
- Verify supported tank sizes (15, 21, 28, 36 gallons) and whether other brands are compatible.
- Steel with powder coating offers durability and weather resistance; aluminum reduces weight but may cost more.
- Foldable designs or D-pin mechanisms can lower physical effort during loading.
- Some models disassemble or fold for easier storage when not in use.
- A clamping system that distributes weight evenly helps protect bumpers from damage.
