What length load bars and mounting feet do I need on an Alu-Cab Contour Canopy to later add a Gen 3R rooftop tent?

We recommend the 1450mm load bars, which give you more flexibility for adding accessories later, especially a Gen3R rooftop tent. You'll also need standard or high-profile mounting feet rather than low-profile feet, which won't provide enough clearance for the tent mounts — measure to confirm which height you need.
