Low range doesn't add traction, it just adds torque multiplication.
Having said that, selecting low range on some implementations does lock the
transfer case--those usually have a warning against using them on non-slick/loose surfaces.
Low range is useful if you ever leave Florida on trips to where there may be actual hills.
Or if you mud crawl in Florida.
Although an all time 4wd or AWD may cost slight gas mileage, it sure does
help handling on wet roads--which Florida does get pretty much every day at 3:15 pm it seems. And if you keep it long enough, the rare snowfall or ice storm may actually occur.
