OK, so your wiper problem was solved by following the tech article...?

As far as towing weight, there are a number of threads that go over this. Since you haven't listed your drivetrain configuration, I suggest a search for something along the lines of "GVWR", "max+tow+weight", etc.

 

havn"t seen the tech article,only just found forum,thanks for gvwr info ,i"ll look it up
