I saw the Remi Shade cab blinds on a Winnebago Sprinter at the local dealer. They didn't sell Thor Synergy Sprinters which was OK because I'm picking up my new Synergy this month from General RV who gave me an unbeatable deal anyway. These Remi Shades are the absolute best cab privacy system I have seen. With vertical pleats they open/close horizontally like bifold doors and store neatly away when not in use. It took several phone calls and a few back and fourth emails with General RV and a Winnebago dealer in Iowa but It was worth it. The blinds are expensive and so is the install labor but by being patient and using a bit of negoatiating I saved around $900.00. In the end I bought the blinds in Iowa at 10% off list price and had them direct shipped to General RV in Michigan who agreed to install them at $650.00 less than their original labor quote. Instead of spending $1900.00 the whole deal parts, labor, shipping was only $1005.00 and I got the best blind system there is for a Mercedes Sprinter cab.
If you want to find out where I bought them just ask.
