My Triton came to me with a Protec cover and a Thule wind out canopy. I have recently fitted the cover and found that water and leaves collect and form a gulley between the canopy and van no matter how much I tension the cover. The canopy also makes the cover a very tight fit which makes adjustment difficult.
Is there something I can put under the cover and in the gulley to prevent this happening?

I think you could be on the right track Roger I'll have a measure up later.
