Can You Put a Roof Top Tent on a Subaru Outback

The Subaru Outback is a popular choice for overlanders and campers, and many owners wonder if a roof top tent (RTT) can be safely mounted. The answer depends on factors like roof load limits, rack compatibility, and proper installation. This guide explains what to check, how to choose the right RTT, and the steps to mount it securely on a Subaru Outback.

Roof Rack Compatibility And Weight Limits

Before selecting an RTT, verify the Outback’s roof rating. Most models allow a dynamic load (during travel) of around 100 pounds and a static load (stationary) of 150 pounds or more, but ratings vary by year and trim. The RTT itself typically weighs between 100 and 200 pounds, depending on size and materials. Add the weight of crossbars, mounting hardware, and any added gear. Exceeding the roof’s weight limit can compromise handling, braking, and safety.

Choosing The Right Roof Rack And Mounting System

Use a sturdy factory or aftermarket roof rack with a high weight rating and appropriate crossbar spread for an RTT. Aluminum crossbars are common for lighter setups, while steel options offer higher rigidity. Look for fully compatible mounting rails or tracks that allow quick, secure attachment of the RTT’s hardware. Ensure the mounting system distributes weight evenly and provides locking mechanisms to prevent theft and movement during transit.

Bedrock Of Safe Installation: Aerodynamics And Clearance

RTTs add wind resistance, which can affect fuel economy and stability at highway speeds. Choose a low-profile tent when possible and ensure the RTT does not obstruct the sunroof or vehicle sensors. Check ground clearance when the tent is deployed and when closed to avoid contact with height-restricted spaces. Proper placement over the roof’s centerline helps balance weight and reduces sway in crosswinds.

Drilling And Attachment Considerations

Many RTT systems do not require drilling into the vehicle roof, relying on clamp-on or rail-based mounting. If a system requires drilling, it is crucial to follow manufacturer instructions precisely and consider a professional installation. Improper mounting can damage the roof, rails, or internal components. Use appropriate hardware, sealant, and torque specifications to prevent leaks and corrosion over time.

Weight Distribution And Vehicle Handling

Outbacks with extra roof weight may feel increased wind buffet and altered handling. To minimize effects, position the tent as low as possible and maintain balanced weight on both sides of the roof rack. Periodically inspect mounting points, hardware tightness, and weather seals. For longer trips, perform a quick check after the first highway run and after any rough road section.

Electrical And Accessory Considerations

RTTs can be paired with interior LED lighting or external awnings, but these add more load and potential electrical draw. If the Outback’s electrical system powers accessories, ensure circuits are rated for the added demand and consider a dedicated battery or portable inverter if necessary. Keep wiring away from sharp edges and moving parts to prevent wear.

Pros And Cons Of An RTT On A Subaru Outback

• Pros: Quick setup for camping, comfortable sleeping height, better weather protection, easy access to sleep setup without tents on the ground.
• Cons: Reduced fuel economy, potential handling changes, higher center of gravity, added wind resistance, potential roof leaks if not sealed properly.

Step-By-Step Installation Overview

1. Confirm roof weight capacity and dealer recommendations for the specific Outback model year.
2. Choose a compatible roof rack with adequate crossbar spacing for the RTT.
3. Assemble and position the RTT on the roof, aligning it with the vehicle’s centerline.
4. Attach mounting hardware per the manufacturer’s instructions, ensuring even torque on all fasteners.
5. Check for clearance and test mounting by applying moderate pressure to ensure secure fit.
6. Inspect seals and weatherproofing around rack rails to prevent leaks.
7. On the road, monitor for any unusual vibrations and retighten hardware if needed after a few miles.

Maintenance And Longevity

Regular maintenance extends RTT life and safety. Clean mounting points, inspect seals for cracking or wear, and re-torque hardware according to the manufacturer’s schedule. When not in use, store the tent securely to prevent wind damage or theft. If the RTT includes an integrated mattress, rotate or air it out periodically to prevent mold and odors.

Alternatives And Considerations

For those concerned about roof load, a ground tent or a free-standing pop-up tent can be viable alternatives. A roof rack-mounted awning or a roof pod can provide extra storage or shelter without adding the weight and wind resistance of a full RTT. Compare total installed weight, ease of setup, and storage needs to determine the best option for the Outback’s usage patterns.

Frequently Asked Questions

• Can a Subaru Outback handle a roof top tent? Yes, with the correct roof rack, proper weight distribution, and adherence to the vehicle’s load limits.
• Do I need professional installation? Not always, but a professional can ensure compatibility and prevent leaks or structural damage.
• Will an RTT affect fuel economy? Yes, due to increased wind resistance and weight; expect lower mpg on many trips.

Key Takeaway: An RTT on a Subaru Outback is feasible and popular when the owner selects a compatible, properly mounting system and respects weight limits, aero considerations, and maintenance. Careful planning and installation ensure safe, enjoyable camping experiences without compromising vehicle performance.
