I have to agree that the High-Lift will become a mess if left outside all the time. I much prefer to have it inside protected so that I know that it is on working order if I need it. I think that moving it outside when you go 4x4ing is a good idea since it will be easy to access (well easier than in the back under all the other stuff).
If you really like the look I would just buy a cheap one and put it up there and never use it a recovery (poser

). I do a bunch of rock climbing and gear is your best friend, treat it well and it will not let you down.
