Conditions that can change the answer
- RV/Travel Trailer use is limited to two bikes.
- The first two tray positions are rated to 65 lb each.
- Use only the published 2" or 2.5" receiver configurations.
- Do not infer RV approval for a Cargo Add-On; 1UP USA lists that accessory as not RV/Travel Trailer rated.
Do not treat this as a safety certification. Your regional product version, vehicle, receiver, rack configuration, bike weights and current manufacturer instructions must all be within their own limits.
