Wow, those are some pretty light weights. My 99 Montero weighed 4970 with just me aboard, so I guess it put on more weight than I'd thought over the years!!

I will also praise the 3.5 and its drivetrain as an excellent tow. I towed our 6000lb boat/trailer to Maine and back with it and in some ways it tows better than the LandCruiser. Of particular appreciation when towing heavy were the 3 way shocks, and the transmission "hold" feature. I also had airbags in the rear coils.
