Based on the uses you described, I would choose the LC because it is a much more comfortable ride, spacious, and has a V8 (especially if you were to add a lot of weight to it, this would be a big plus). Long trips in the LC are amazing.
Why not spend a bit more for a newer land cruiser (equal to or less than you'd spend on the 4runner) if you are considering a land cruiser? Also, waiting 6-8 months for a 4Runner seems ridiculous.
I think my only other question would be, what are you driving now?
