Thule Range 9057 (905700): RV compatibility
Current four-bike hanging rack whose product page approves motorized-RV travel only at reduced load capacity; the model-specific fitting instruction separately says not to install it on a trailer or other towed vehicle.

Manufacturer guidance by RV use
Fifth wheel
The model-specific fitting instruction says not to install Thule Range on a trailer or other towed vehicle; a fifth wheel is therefore outside the permitted installation shown by the current instruction.
Travel trailer
The model-specific fitting instruction says not to install Thule Range on a trailer or other towed vehicle, despite broader product-page marketing language that mentions RV/travel-trailer duty.
Flat-towed vehicle
The model-specific fitting instruction says not to install the rack on a trailer or other towed vehicle, so do not mount this rack on a flat-towed vehicle.
Evidence note: Current Thule sources conflict at the marketing-copy level: the product page describes Range as built for forces at the back of an RV/travel trailer, while the model-specific fitting instruction says “Do not install on a trailer or other towed vehicle.” RV Rack Check follows the more specific installation instruction, so travel-trailer, fifth-wheel and flat-towed-vehicle use are marked manufacturer excluded.

Conditions that can change the answer
- This record covers current U.S. model 9057 / retail code 905700.
- The product page publishes 150 lb total road load capacity and 37.5 lb maximum bike weight; do not treat those road ratings as unchanged motorized-RV limits.
- For motorized-RV travel, follow Thule’s current 40% load-reduction guidance and the exact current fitting instruction.
- Current fitting instruction: hitch-pin-hole depth must be at least 1.5 inches.
- Do not install on a trailer or other towed vehicle.
Before you travel: confirm the exact rack variant, current manufacturer manual, receiver and hitch rating, bike weights, permitted adapters/extensions and any reduced RV-specific load limit.
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.
