Mines happily bonded under the pop top on the van not in the gutter. Bent it every so slightly to match the contour of the van, triple checked its position, bonded with Sikaflex, held in place overnight with Guerilla tape. I used normal aluminium caravan rail. Holds a Khyam Pro4 inflatable awning just fine. Don't get fooled into spending hundreds if you are just having an awning and don't puncture the van with screws in a position you can't then use rust prevention to stop corrosion.Hi mate. I have just bought an S+S multirail and I'm looking to bond it on and not use screws. Can you give any tips or info as to how you did it? The rail is flat and straight and it looks like the screws help to form it to the van. Did you bend the rail first and if so how did you do it? Also, how did you keep the rail clamped to the van whilst the adhesive went off? Cheers.
