During non-summer with weather back and forth I get tired of trying to insert that bottom section down cause its so tight, and lately just leave the sides zipped down, and the bottom edge unclipped. It overlaps anyway so rain doesn't enter the cab there. Because the next day it will be hot and I need to roll it up and take the doors off, LOL. I know that doesn't answer your question, but maybe your needs are similar to mine since you're in Texas nearby.
