Thanks for that but I’m moving away from roof rack I have underground parking and can fit my van in that but won’t with a roof rack. Hence the reason to hang inside.
It's better if you can slide it in on edge along a shelf that has a lip on the outside edge. I fitted my shelf down the right hand side side, in line with the edge of the cargo area, so that I can simply slide it in and out with very little effort and without having to get in the van. A short bungee and single hook secures it in place. The shelf is an offcut of plastic soffit.Sorry Max missed your post...self tapping screw/bolts into the channels which run across (from one side to the other side) the roof - just make sure they are short enough not to pierce the roof - and go for a fairly deep thread so it's nice and secure, perhaps secure in 2-3 places on each hook so it's as firm as..?
