Wow, lots of great info in this thread.
I had a HJ60, really liked it but it would loose a drag race with a fully loaded school bus.
Not a problem on the highway and good fuel mileage for a Land Cruiser.
Lifted with 33's and it wheeled off road just fine.
I now have a LJ77 with the dreaded 2LT. Mine is from the European market and I have not had an issue with overheating even running a/c in the summer. Still not a drag racer but definitely quicker than a HJ or FJ.
Also lifted and on 33's. I have not wheeled anything difficult but it seems capable.
Road salt destroyed my HJ60. Lots of trips to upstate NY, brown truck was white with salt. Rust finally got to it.
I did try to wash it frequently but should have had the frame and undersides treated. I did make it to the 500K mark (km not miles).
I have 320K (km) on the LJ and expect it to make 500K also.
Surprisingly, the LJ is very close in size to my FJ55, so there is room for hauling camping equipment.
If you do not need the full rear seat, the LJ has split rear seats, so you could fold one half down for more storage.
However, there is also 3rd row seating if you have more passengers but storage will be limited.
Good luck in your search.
