Don't know if anyone would want to do this besides myself; however...

Is it possible to switch the two sliding rear side windows, move the left to the right and right to the left?  I'd like to have the opening portion of the window further back.  Talking "late model" 2001-03 Eurovan.

If it is possible, what are the down sides of doing so? 

Is this a DYI or do I need to get the window guys to come out?  If not DYI, do I need special window guys or will most any of the usual companies manage?

That's one in the bag.  Thks y'al
