Hey Jim, I was talking to Jim Siezemore, from RV outfitters in Bend Oregon about the shade conversion , and he said that he spaces the side pillar covers out slightly and sizes the blinds to ride on them perfectly, I know he's not that close to you but he is a nice guy and would probably answer all your questions, he quoted me around $2400.00 to install the dual front shades, valance and two manual side blinds. $ 750.00 for the front blinds un-installed.
