Thanks for the input guys. My budget definitely keeps me out of the Benz, but the FG4x4s look interesting. I'll look more into those.
I know the t100s are scarce and can be pricey(compared to similar year trucks) , but I like the size and there is a familiarity there due to my previous expedition vehicle being an early 90s toyota truck, plus I've heard nothing but good things from anyone who has owned one with the 3.4l engine.
