When we still had our 08 Vectra, we ordered shades for the whole coach from MCD. All except for the cockpit. They sent me a form to do our measurments on and then I faxed it to them to make the shades. They are very nice and easy folks to work with. And per their instructions all the shades fit perfectly when we put them in. It is quite a job when you have to remove the valances so we had someone do it for us. We replaced all the pleated shades, but left the front as a curtain. If you are going to get the one that is motorized, they will tell you that either them or an autorized installer that was trained by them should install it. The measuring for the cockpit can be pretty tricky and if you do it wrong it's your mistake
I know the MCD folks will be at GNR only to do measuring, not installing. You would have to have Winnebago or someone they trained do that. Well, we now have the 2013 Tour that came with the shades and they are wonderful. Good luck whatever you decide.
