Hi how did u attach them to roof cheers andy
My van came with ply sides and so I put two slats of 25mm x 100mm wood across the top edges and reinforced the joins with wooden blocks.Then I used the U brackets that are for the pipes to fix in place. I just used 3" pipes but you would need bigger if above 25ft poles.
Yep....2 soil pipes,threaded bar and munsen rings from screwfix.....works well for pole storage.....
