Curious question.....on the vehicles the company i work for builds we use dual electric wiper motors instead of one with long linkages.....anyone ever
do this on our coaches? I thought i saw one done over in the GMC Photo's but not sure.

Sir, I have not done it on a coach but I have a Kenworth W-900A model with separate air operated wipers. In the 30 years of owning that truck I have
yet to get them to stay in sync, and I have tried every time it rained. I don’t think electric would be any different.

I've always wanted to pursue Pantagraph wipers like the buses have that go side to side and cover the entire Windshield.   There was a GMC up-fitter called Silver Motor Coach that did that and they looked awesome.   They also made a 28' coach,, a 32' and a 34'   The OEM wiper system for the passenger side is basically useless. Sent from my U.S.Cellular© Smartphone
 
Eric Tanner did one where the wipers go in opposite direction and park
in the middle.

When I had my 3rd GMC, I was looking at the pantograph assemblies off of Blue Bird TC2000 with their wiper systems. I'd like to see how they would be,
as I think they would beat the system we currently have...My concern was the curvature of the glass, the TC2000 doesn't have a huge sweep...
