Roof rack sliding off

[threedogs]

Mine is a tigerz11 roof top rack which will carry the roof top tent in the rear and a kayak mount (which is mounted at the two front bars) and some jerry on the front

I clamped it to the gutter and it looks pretty solid but still wondered if it would be sufficient. Daily checks might indeed be the key!

Try to avoid steel on steel when you mount it, cut some rubber so it absorbs a few vibrations
and it also allows a little give. Daily checks would be manitory in my books.
