Now that you saved $30+, go to Home Depot or Lowes and buy 2, 1/2 pipe insulation foam tubes, 3' long (or what ever size they come in 3 or 4ft) and slide them up over the blade to keep the sun from drying out the rubber blade. Cost about another $3. Of course if you are on the road everyday with the MH then it could be a pain. but if you are setup for any amount of time it is well worth it.
