I like the one from GoWesty (over the other well known list vendor).
Excellent quality and fit.  I've put two of them on different vans, but
last one bought about two years ago....not sure if they still carry the
same one.

The ones I bought have a slightly vertical "ribbed" texture on the
outside...slightly rough to the touch vs. the slick shiny rubbery ones from
the other vendor.

My 2 cents.
