Having a lsd (lunchbox) locker in the front on a daily driver can be a little interesting at times, depending on your climate. Since you are in Florida, you could probably do it, and never even notice it on the road.
With Snow however, the locker in the front will make your jeep tend to 'plow' through the snow more often. It takes some getting used to, but alot of people do it. I did it for years in Iowa with my TJ.
You will notice some clicking when turning onroad, some lockers are louder than others.
A selectable (air, electric or cable) is the best choice, but it is also the most expensive choice.
