Jeep trips are fun, but thats hecka long trip in a CJ5. Your young, but U still may need a kidney transplant after all those miles.
If your jeep can make it or not?... only U can say. How dependable is it? No one can say if what U break is hard to fix... since U could break just about anything in a rig that old.
Does it have an overdrive? Sounds like it does'nt since U mentioned not going over 60mph. Gas mpg could really suk???
I think I'd have some serious first thoughts.
Good luck if ya do it.
