Since we removed the blinds in the RV it was necessary to find some method for privacy. Price was also a huge consideration in deciding to go with blinds or shades. I even considered doing a mirrored one-way glass tinting. Ultimately we settled on shades. Lowe’s had these 6 mil. bright white Levelor shades for $7-11 each and even cut them to size for free. Word of advice, plan on this process taking an hour and a half or more. More advice: don’t go with your wife, almost 2 year old and 5 month old. Make sure to measure from either mount-to-mount or material width. If you don’t tell the person cutting them, they will likely choose the wrong way. It’s also a good idea to measure them after they cut and before you purchase the shades. I learned the hard way on this one and had no less than three trips to Lowe’s to make this right. I also found that 1.5″ either side of the window was the minimum added width for ensuring the shade provides proper light blocking and privacy.
