Purchased a MUX 4 weeks ago, very happy so far, tows our Olympic Javelin SP 18'6" van well. Unfortunately drivers side mirror was broken by a stray tree branch. Stories of $500 replacements on the net proved not to be true. A new mirror glass was $56 from dealer and to remove and fit new one is very easy (YouTube replacing mirror on Isuzu Dmax) is exactly the same procedure, takes 5 mins. Replacing the entire mirror assembly would be a whole different story.
