I am looking for the same thing right now. there are some out there, but they are expensive. See this link for ex.

The "gold standard" seem to be the mirrors from ProEFX - but $300 plus is a bit steep. I have already purchased and returned two sets of universal mirrors that did not fit securely however...including the CIPA mirrors sold by Camping World. Wondering if the $30 suction cuppy ones at Walmart actually work...getting frustrated enough to spend the big money soon.
ProEfx and Tyger are the two I just found again, but there is a third similar brand, and I will keep looking for it - slightly cheaper at around $200 but in a pebbly black finish only, IIRC...
PLEASE let me know if you come up with something that works! Going camping again next weekend!
