Load Calculation Formula:
From: | To: |
Rooftop tent load rating refers to the maximum weight capacity that a rooftop tent and its supporting vehicle roof can safely handle. This includes the weight of the tent itself plus all occupants and their gear.
The calculator uses a simple formula:
Where:
Explanation: This calculation helps ensure you don't exceed your vehicle's roof load capacity and the tent's maximum weight rating.
Details: Proper load calculation is essential for vehicle safety, preventing roof damage, and ensuring the structural integrity of both your vehicle and rooftop tent during use.
Tips: Enter the tent weight (usually found in product specifications) and the combined weight of all occupants who will use the tent simultaneously. Always check your vehicle's roof load capacity before installation.
Q1: What is a typical rooftop tent weight?
A: Rooftop tents typically weigh between 45-90 kg, with hardshell models generally being heavier than softshell ones.
Q2: How do I find my vehicle's roof load capacity?
A: Check your vehicle's owner's manual or contact the manufacturer. Most vehicles have a dynamic (while moving) and static (when parked) load rating.
Q3: Should I include gear weight in this calculation?
A: Yes, any additional gear stored in or on the tent should be included in the total load calculation for safety.
Q4: What's the safety margin I should maintain?
A: It's recommended to stay at least 10-20% below the maximum rated capacity to account for dynamic forces during travel.
Q5: Does this calculation include the roof rack weight?
A: No, this calculator only considers the tent and occupants. The roof rack weight should be considered separately in your total roof load calculation.
