As already stated, think of the recovery use. Hi-Lift's can be used as a winching device! 60" gives more room to pull when needed. Also, when you are on a trail, you never know when you are breaking down. Some times it happens in the rocks, or trees, when you need to jack up to do a quick fix. I say 60", I have the 60" and no, I have not used the full travel on it, but it is nice to think that I will not have to scavange for wood blocks for a few extra inches, when that time comes and I need that 1' more!
