Toughest, most capable was probably my ‘73 Toyota Land Cruiser. Most character was my ‘47 Willy’s Jeep. Most all around and comfortable, my current ride, ‘17 Tundra TRD Pro.
i have a 42ford"script" jeep, 44ford, 45willys, 48willyw 53M38a1, 10/72 fj40.
I would say those early jeeps and the cruiser went in the mud and up places where the newer vehicles were stuck.
the 10/ 72 has a later six cylinder engine, converted to 4speed, and other stuff done to it.
i get offers to sell them all the time, nope.
