A Guide to Vehicle Load Ratings **By Bushbuck Team — February 21, 2025** **Category:** How-Tos | **Tags:** how-tos --- ## 📖 Overview Thinking about adding a [rooftop tent](https://bushbuck.co.nz/collections/rooftop-tents-camping) to your 4WD, ute, or SUV? Before you make the leap, there’s one crucial question to answer: *Can your vehicle handle the weight?* Every vehicle has load limits, set by the manufacturer. Exceeding load limits can affect the safety and performance of your vehicle on the road, potentially increasing the likelihood of accidents and damage. In Australia, getting caught “overloading” can even result in a hefty fine. We get a lot of questions from customers about vehicle load ratings, roof racks, and off-road weight limits. So, we’re setting the record straight on everything you need to know before mounting a rooftop tent to your vehicle. --- ## Understanding Vehicle Load Ratings A vehicle's load rating refers to the **maximum weight that its roof can safely handle**, which includes any items you place on it like awnings, roof boxes, bicycles, solar panels and, of course, rooftop tents. If you have a ute, you’ll usually find** the tub and/or canopy have much higher load ratings** than the roof so make sure to check your vehicle’s user manual or ask the manufacturer. Before mounting a [**rooftop tent**](https://bushbuck.co.nz/collections/rooftop-tents-camping), you need to know three key numbers: **dynamic load rating, static load rating, and roof rack/crossbar ratings**. There’s one more unofficial rating to keep in mind, but we’ll cover that further down. [Image: Asset reference] ### ### **Dynamic Load Rating (While Driving)** This is the **maximum weight your vehicle’s roof can handle while in motion**. It’s the number that really matters when you’re considering a rooftop tent. - Most vehicles have a **dynamic load rating between 50kg and 100kg**. - This includes the weight of the **roof rack, rooftop tent, and anything else you’re carrying up top**. - Exceeding this rating can mess with your vehicle’s handling, increase your chances of rolling your vehicle or having an accident, and even cause damage to the roof. *Example:* The Toyota Land Cruiser has a **dynamic load rating of around 100kg **(varies between models). The [**Bushbuck Armourdillo® Rooftop Tent**](https://bushbuck.co.nz/products/armourdillo-aluminium-rooftop-tent?variant=40159636095075)** **(hard shell) weighs **80-90kg**, while the **Bushbuck **[**Ardvark Rooftop Tent**](https://bushbuck.co.nz/products/ardvark-rooftop-tent?variant=42652448817251) (soft shell) weighs **44kg **(without the detachable ladder). Add in roof racks (approximately 20kg, depending on make and model) and you’re getting pretty close to the dynamic limit with the Armourdillo®, but you’ve got plenty of wiggle room with the Ardvark. ### ### **Static Load Rating (When Parked)** This is the **maximum weight your roof can support when stationary**. Because the weight is evenly distributed while parked, the static rating is usually much higher than the dynamic rating. - Most vehicles can handle **200kg to 400kg** when stationary. - This accounts for the weight of the tent, roof racks, and the **occupants sleeping inside**. *Note: *Many rooftop tents, including the **Bushbuck Armourdillo** and **Ardvark**, are designed with **a built-in ladder that helps distribute weight**, reducing the strain on your vehicle’s roof. This means that while your tent may weigh 80kg, part of that load is supported by the ladder, increasing the overall effective static load rating. Unless you’re an advanced mathematician, it’s not possible to calculate exactly how much weight the ladder takes (will depend on many factors), but it could be up to 5% if set up correctly. *Example:* A Ford Ranger’s **static load rating is around 300kg**, which is more than enough for either Bushbuck rooftop tent, plus two adults and extra gear. But the **dynamic load rating** is your most important consideration and that’s only around **75kg **for a Ranger** **(depending on the model). ### ### **Roof Rack and Crossbar Load Ratings** Even if your vehicle can handle the weight, your **roof racks or crossbars** need to be up to the task too. - Roof racks typically have their **own weight limit**, separate from the vehicle. - **Factory-fitted rails** are often too weak for rooftop tents—**aftermarket heavy-duty racks** are recommended. - Some crossbars have a **dynamic rating as low as 50kg**, so always check before loading up. We recommend going with roof racks with load ratings of at least 100kg for the [**Armourdillo®**](https://bushbuck.co.nz/products/armourdillo-aluminium-rooftop-tent?variant=40159636095075) and 75kg for the [**Ardvark**](https://bushbuck.co.nz/products/ardvark-rooftop-tent?variant=42652448817251). It’s always best to go with racks and crossbars that can handle more weight than you need to be on the safe side ### ### **Why Do Vehicle Load Ratings Seem So Low?** [Image: Asset reference] You might be surprised at just how low manufacturers set their vehicle load ratings, especially when the vehicles are marketed as tough, all-terrain work horses.  We can only speculate that manufacturers are being extra cautious and conservative when it comes to setting these limits. Put it this way, if you flipped a Toyota Land Cruiser upside down, there’s every chance the roof would hold the weight of the vehicle, which is roughly 2000kg, just fine. And yet, the Land Cruiser’s static load rating is less than 300kg. However, safety on our roads is of the utmost importance, so we always recommend adhering to the limits as set by your vehicle manufacturer—even if you reckon your vehicle can handle more weight. --- ## Off-Road Load Limits: A Whole Different Ball Game If you’re planning to take your [**rooftop tent**](https://bushbuck.co.nz/collections/rooftop-tents-camping) **off-road**, things change. Most vehicle manufacturers set their load ratings for **sealed roads**. But when you’re bouncing around on rough terrain, the forces acting on your roof increase dramatically. That’s why many brands **reduce their load rating by 30-50%** for off-road use. *As far as we can tell, the off-road load rating typically applies to roof racks and crossbars, but you may be able to ask your vehicle manufacturer for their recommendations.* We know this might sound a bit extreme—surely hardcore 4WD vehicles are built for hardcore off-roading, right? It really depends on how hard you’re pushing your vehicle and, at the end of the day, it’s up to you to “weigh up” the risk.  - A vehicle with a **75kg dynamic load rating on-road** might only have a **37.5kg rating off-road**. - If you’re planning **river crossings, steep inclines, or corrugated tracks**, go for **a lighter rooftop tent** like the [**Bushbuck Ardvark**](https://bushbuck.co.nz/products/ardvark-rooftop-tent?variant=42652448817251). ## ## **Legal Considerations in New Zealand and Australia** ### ** New Zealand** - NZTA doesn’t specify an exact fine for exceeding roof load ratings, but overloading **can result in a failed Warrant of Fitness (WoF)** and **liability in an accident**. - Police and compliance officers can issue fines if your load is deemed unsafe. ### ### **Australia** Australia takes roof load limits **seriously** and you can face serious penalties for overloading. - Fines for exceeding vehicle load limits vary from state to state, but **can be in excess of $1000** along with penalty (demerit) points for each offence. - Transport authorities have **cracked down on overloaded 4WDs**, especially those with **rooftop tents, awnings, and extra gear**. - Most insurance companies **won’t cover damages** if your vehicle is overloaded. --- ## How to Check If Your Vehicle is Rooftop Tent Ready Not sure if your setup is good to go? Follow this checklist: - **Check your owner’s manual** for your vehicle’s **dynamic and static load rating**. - **Look up your roof rack’s load rating**—not all racks are rated for rooftop tents. - **Factor in everything on the roof** (tent, racks, ladders, gear) to stay within limits. - **Consider a lightweight tent** (like the Bushbuck Ardvark) for smaller vehicles or off-road adventures. - **Stick to legal weight limits** in NZ and Australia to avoid fines and safety issues. ## ## **Know Your Limits ** Load ratings might not be the most exciting part of gearing up for an adventure, but they’re an important consideration when buying a rooftop tent. Overloading your roof can throw off your handling, wreck your suspension, and even get you slapped with a hefty fine. Whether you’re tackling a gnarly off-road track or cruising to your next campsite, knowing your load limits keeps you—and everyone else on the road—safe. Adventure awaits—just make sure your rig is ready for it. *Got questions about rooftop tents? *[*Get in touch*](https://bushbuck.co.nz/pages/contact-us)*—we’re always happy to help.* --- ## Related Articles - *[Bushbuck Armourdillo Rooftop Tent Comparison](/blogs/campfire-chats/bushbuck-armourdillo-rooftop-tent-comparison)* - *[Armourdillo in Action: Reviews of Bushbuck's Rooftop Tent](/blogs/campfire-chats/armourdillo-rooftop-tent-reviews)* - *[Bushbuck Armourdillo Rooftop Tent Review 2025 Ollie Craig](/blogs/campfire-chats/bushbuck-armourdillo-rooftop-tent-review-ollie-craig)* - *[A Complete Guide to Buying a Rooftop Tent: Everything You Need to Know](/blogs/campfire-chats/guide-to-buying-a-rooftop-tent)* - *[7 Best Off-Road Camping Spots in New Zealand: Where to Go with Your Rooftop Tent ](/blogs/campfire-chats/best-off-road-camping-spots-nz)* - *[How to Choose the Best Tent for Camping & Hiking](/blogs/campfire-chats/how-to-choose-the-best-tent-for-camping-and-hiking)* ---
