I have both.
I use the 48 incher for general duties around my FJ40. I've never needed more. I don't believe I've ever used it to change a tire, the stock bottle jack is way safer for that.
For the 80, it's so flexy, that the 60 incher is almost mandatory. It's also easier to carry a longer bar on a big truck. Again, tires get changed with the bottle jack and the hilift is mostly forgetting the tire out of a hole or moving the truck around a bit.
For everyone with a different brand of truck, you should try and get yourself a Toyota bottle jack. They have come with Land Cruisers and Mini-trucks since the biginning of time. They are awesome works of art, especially the old cast ones. They are extremely useful, safe, compact, not too heavy etc. The best design of it's type I have seen. I carry two, and not only use them to jack the axle, but they make great jack stands too.
Back to the original poster-I would get the 60 inch model. If you end up not using the extra foot, cut it off. Put the jack in/on the truck only for 4 wheeling trips and it should stay free of significant rust for decades.
