Rooftop tents (RTTs) are a versatile and comfortable way to camp, but they do require some planning before purchase and installation. The considerations below apply to most rooftop tents, regardless of brand or model.

Vehicle compatibility
Not all vehicles are suitable for rooftop tent use. You should confirm that your vehicle’s dynamic and static roof load ratings are sufficient for the tent, occupants, and any additional gear. Always refer to your vehicle manufacturer’s specifications.

Roof racks and mounting
A compatible roof rack or crossbar system is required to mount a rooftop tent. Racks must be properly rated for rooftop tent use and securely installed. Some tents are heavier or larger than others, which may influence rack selection.

Tent weight and size
Rooftop tents vary in weight, footprint, and folded height. Consider:

• overall vehicle height once installed

• garage or parking clearance

• ease of opening and closing the tent

Heavier tents may require assistance for installation or removal.

Installation considerations
Most rooftop tents are designed to be installed by the customer using basic tools, but installation may require:

• lifting the tent onto the vehicle

• aligning mounting hardware

• ensuring even weight distribution

Some customers choose to have installation performed by a professional or with the help of a second person.

Access and daily use
Think about how often you’ll open and close the tent and how you’ll access it when deployed. Ladder placement, door orientation, and vehicle height can all affect ease of use.

Driving and handling
Adding a rooftop tent changes your vehicle’s weight distribution and center of gravity. You may notice differences in:

• handling

• braking

• fuel efficiency

These effects vary by vehicle, tent size, and driving conditions.

Questions before ordering
If you’re new to rooftop tents or unsure about compatibility, fit, or installation, we encourage you to contact us before placing your order. Our team is happy to help you make an informed decision.

Large items such as rooftop tents, kayaks, electric surfboards, e-foils, and similar equipment are typically shipped via freight carriers rather than standard parcel services.

Delivery scheduling:
Freight carriers usually contact you to schedule a delivery appointment once the shipment reaches your local terminal.

Delivery location:
Freight deliveries are typically curbside. Drivers are not required to bring items inside or assist with installation.

Inspection upon delivery:
We recommend inspecting the shipment at delivery and noting any visible damage with the carrier before signing.

Questions before ordering:
If you have questions about access, delivery requirements, or whether freight shipping is right for your location, our team is happy to help before you place your order. See our Pre-Purchase FAQs.
