Rooftop Tents: Hidden Strains and Costly Consequences for UK Drivers

Strategic Insights -

Road trippers, festival-goers, and campers often rely on rooftop tents for convenient and practical accommodation, but temporary car insurance experts at Tempcover warn UK drivers about the significant strain these can place on vehicles and the costly consequences of getting it wrong. When considering a rooftop tent, drivers must be aware of the two key weight limits: static roof load and dynamic roof load. Static roof load refers to the weight a vehicle's roof can support while stationary, whereas dynamic roof load is the much lower weight it can safely carry on the roof while driving. Many drivers mistakenly assume that if their car can support the weight of a rooftop tent while parked, it is safe to drive with it too. However, this assumption can lead to costly consequences.

Key Takeaways:

  • There are two key weight limits for rooftop tents: static roof load and dynamic roof load.
  • Dynamic roof load is the much lower weight a vehicle can safely carry on the roof while driving, which includes the combined weight of the tent, roof bars, and mounting kit.
  • Adding weight from rooftop tents can place significant strain on a vehicle's suspension system, especially in smaller or lower cars.
  • Beware that even if a rooftop tent technically fits your vehicle, the combined weight of the tent and roof bars can affect suspension performance, reduce speed, and increase fuel consumption.
  • Always check the manufacturer's guidelines for the specific vehicle make and model.
  • Reduce speed when driving with a rooftop tent to offset the drop in fuel economy and maintain control.
  • Consider the added wind resistance, noise inside the cabin, and crosswinds when driving with a rooftop tent.
  • Make sure to secure the tent box properly and avoid leaving it on the roof when not in use.
  • Declare all modifications to the insurer, including bars and the tent box.
  • Consider adding security measures to protect the tent box from theft.
  • Be aware of the potential reduction in fuel economy due to increased drag and rolling resistance.

Statistics:

  • The average reduction in fuel economy due to rooftop tents and roof bars is 2-5%.
  • This could lead to an extra £2.30 in fuel on a 300-mile round trip.
  • Failure to safely secure roof-mounted equipment can result in a £2,500 fine, three penalty points, and a potential driving ban.
  • Many motorists may mistakenly believe their tent box is covered under standard vehicle insurance, which can lead to costly consequences.
