That's a connection more or less in name only. Much like the connection between a military hummer and an H3. The 1950 FJ and BJ was a jeep knockoff with a cloth roof. https://www.fj.co/blog/history-of-the-toyota-fj-series/ http://www.toyota-global.com/showroom/vehicle_heritage/landc...

The FJ40 from 1960 is somewhat comparable, but weighed 1/2 (3263 lbs) what the modern beast weighs.

The FJ60 (http://tlc4x4.com/fj60.htm#sthash.nB2cpi4h.dpbs) from 1981 was even closer and heavy at 4246 lbs, but again still 1,500 lb lighter than the current version.

Meh. The Chevy Suburban has been in near continuous production since 1929. The gap? When they used the factories that made them to turn out tanks for WWII.
