Building a RV garage input needed. Pictures helpful

My door is 14 ft wide, much easier than 12 ft wide when backing into a dark (even with lights on) garage. Door is 13.5 ft tall. I decided that skylights was a bad choice in the Texas heat. Instead with the side walls being 15 ft tall, several wall panels are just 8 ft tall with an 8 ft Lexan panel above it. These are on the south and east sides and provide good light in the winter months but minimal heat in the summer months.
