In short
Roof bars must fix to structural points or maker-approved systems. Load and height affect payload and ITV depending on project—we install with workshop discipline.
Before you start
- Confirm bike, box, or roof tent weight.
- Check total height with bars and load for car parks.
- Coordinate with solar panel and roof hatch.
- Ask if roof changes need a reform.
Anchoring systems
OEM bars, adapted rails, or feet on factory points by model. Alexis avoids crushing thin skin without load spread. Some vans mark points in the manual; others need model-specific kits. At Belcampers we fit and road-test gently before handing over a van with 20 kg bikes aloft.
Load and aerodynamics
Payload includes everything: interior build plus roof load. Tall box hurts fuel and crosswind stability on the AP-7. Hard vs soft tent changes weight and mounting. We suggest removing roof load in town when unused. Bar height can exceed 2 m—remember parking garages.
Integration with other roof gear
Ideal order: sealed hatch and solar, then bars without crushing foreign frames. Solar cable under bar with protection. Seasonal bar swaps need access without breaking solar seals. Girona kayak summer vs ski winter are different load plans.
Homologación
Bars alone may not change papers; structural roof changes may. We guide via homologación page by modification list. ITV may inspect height and fixing after incidents. Prudent paperwork on mixed camper/work loads.
Common mistakes
- Generic bars on flexible roof skin.
- Ignoring total height and scraping car parks.
- Bars clamped over hatch frame sharing loads wrongly.
When to bring it to the workshop
Need bars for bikes or a box? Safe fitting at Belcampers Girona.
FAQ
Fixed or removable bars?
By use. Removable cuts drag when travelling unloaded.
Do they affect camper homologación?
Depends on full modification set—we review in project.
