A brief explanation on how roof load limits work, and why it's safe to install a TentBox roof tent to your vehicle
In short, as long as the weight of the TentBox you are buying is less than your vehicle roof load limit, then you're good-to-go. The same applies to your crossbar limit.
Whenever roof bar or vehicle manufacturers quote a roof load limit, they are always referring to the dynamic limit, explained further below.
The weights of the respective TentBox models are as follows:
Please note: 99.5% of vehicles will are compatible with at least one of our TentBox models. If you have any questions or want reassurance, please get in touch with our support team.
Dynamic vs. Static Loads
Your vehicle's static roof load limit is at least 5 times the dynamic roof load limit quoted by your vehicle manufacturer.
A dynamic load refers to the maximum weight allowed whilst your vehicle is moving, and the static load is when your vehicle is stationary.
When considering the added weight of people inside the TentBox, you should use the static load limit of your vehicle. You can work this out by multiplying the dynamic load (listed in your vehicle handbook) by 5.
