Lainey: I am in the process of experimenting with a tarp attachment on my van.
I cut a slot in an 8' piece of grey pvc tube (conduit) intended for electrical
wiring. I attached the tube to the roof rack with zip ties and string loops
threaded through the back of the tube.
More to the point, I intend to attach a blue poly tarp to the tube by folding
over a couple of inches along the edge of the tarp around a piece of 1/4" poly
rope, and sliding the folded tarp and rope into the slot in the tube. I
tested this, and the piece of rope held the tarp well. To remove the tarp,
just pull out the rope, and the tarp slides out of the slot in the tube.
Whether it works on the van as an awning
I haven't yet tried, but using a
piece of rope to hold the tarp in the tube sure seems to work.
