“Can my car take a rooftop tent?” is the question end users ask. The question a distributor needs answered is narrower: what has to be true for a given vehicle, and what do I need to collect before I place an order? This page is that checklist.
1. Roof load rating – dynamic and static
These are two different numbers and only one of them applies while the vehicle is moving. The dynamic rating is what the roof and rack carry in motion; the static rating is what they carry parked, which is when people are actually inside the tent.
Ask the vehicle manufacturer for both. Where a market does not publish a roof rating, treat that as unresolved rather than as permission – it is the single most common source of dispute after a sale.
2. Rack type and crossbar spread
A rooftop tent does not bolt to the roof; it bolts to a rack. Three situations:
- Hard-fixed rack. Bolted or screwed to the roof structure. This is the base case, and the one to aim for.
- Factory rails with aftermarket crossbars. Workable, but the crossbars have to be rated for the load and the spread has to fall inside the tent’s mounting channel range.
- Bare roof. Not a dead end – a load-bearing crossbar set can usually be specified – but it has to be engineered for that vehicle, not improvised.
Two dimensions decide it in practice. From our fitting instructions: a crossbar spread of 70-90 cm suits most models and 110 cm is the practical upper limit; bar and rack thickness should not exceed 25 mm, because above that the standard bolt length no longer reaches – you need longer bolts, or a gap of at least 30 mm between the roof and the rack.
Send the centre-to-centre dimension with the enquiry; if it sits outside that range, the answer is a different bar set or a different tent, not a workaround.
3. Model year and roof shape
Same nameplate, different year, different roof. What we need:
- Make, model, model year and trim
- Whether the roof is flat, has raised rails, a sunroof, a shark-fin antenna or a factory rail that runs out before the tent footprint ends
- A photo of the roof and, where you have it, the mounting point drawing
Curvature matters because the tent mounts on a flat plane; a roof that curves across the footprint needs different feet or a different bar height.
4. Total installed weight
Rack plus tent plus occupants plus gear, compared against the dynamic rating with the vehicle loaded. Our aluminium hard shells run 52-80 kg depending on shell size; the PK23 topper unit is 100 kg in aluminium and 150 kg in steel. Add the sleepers and their kit before you compare against the vehicle figure.
Sedans and low-roof cars: the honest answer
Most sedans are not published with a roof load rating, and many have no hard mounting points at all. That does not automatically rule them out – a rated crossbar set can often be specified – but it does mean the decision has to be made per vehicle, on the manufacturer’s figures, not on a general rule.
If a customer wants to fit a tent to a sedan, the sequence is: confirm the roof rating in writing, confirm what the mounts attach to, then choose the tent. In that order.
Fitment checklist
| Check | Why it decides the answer | What to send |
|---|---|---|
| Roof dynamic load rating | What the roof carries while driving | Manufacturer figure or page reference |
| Roof static load rating | What it carries parked, with people inside | Manufacturer figure, or state that it is not published |
| Rack type | Hard-fixed, factory rails, or bare roof | Photo and part number if available |
| Crossbar spread | Must fall inside the tent mounting range | Centre-to-centre dimension (70-90 cm typical, 110 cm max) |
| Model year and trim | Roofs change between years | Make, model, year, trim |
| Roof features | Sunroof, rails, antenna, curvature affect mounting | Roof photo |
| Intended occupancy | Sets the shell size and total installed weight | Sleeping capacity required |
What to send with your enquiry
Send the checklist above with the models you are considering and the volumes. Where a vehicle is tooled already we will say so – the PK23, for example, is tooled for the Toyota Tundra and Ford F-150 beds and made to order for other pickups. Where it is not, we will tell you what drawing or sample we need to confirm it.
MOQ depends on model and customisation, warranty is 12 months. Start at the enquiry form.
