Im in Phoenix AZ, so 70% of the year its crazy nice outside and not hot. I take the truck off-roading during this time of the year. During this time I run the half doors for the open-air experience. My truck is stored inside a garage so security not an issue. However, in the middle of the summer we get up to 118f so for those couple of months, plus a couple in the dead of winter I run the full x doors so I have air conditioning and heat. I want a way to switch between these doors without having to unbolt all the strikers etc. Thats basically why i have two sets of doors.
