Buying Guide
What to consider when choosing 18-foot trailer accessories
- Trailer type and bunk size: Confirm your bunk width and length (18 ft x 18 in is a common size) to ensure the carpet covers the bunks fully.
- Material and durability: Look for UV resistance, quick-drying surface, and a sturdy backing to withstand outdoor exposure and years of use.
- Installation method: Some bunk carpets require glue or staples; others may use clips or ties. Check whether you need adhesive, staples, or tools included.
- Protection needs: If hull protection is a priority, prioritize higher pile carpets or thicker backing; for general protection, 5–8 mm thickness is typically sufficient.
- Weather and environment: For boats frequently in sun, UV stabilization is valuable. For dusty or sandy environments, abrasion resistance matters.
- Tarps and tarp systems: For loads that require weather protection, prioritize reinforced hems, rust-resistant grommets, and anti-sail features to reduce wind lift.
- Storage and maintenance: Consider tarps with easy-clean materials and bunk carpets that dry quickly to prevent mildew.
