That’s a fine piece of pressure treated lumber securely strapped to this Mercedes S Class. So secure it’s actually bowing.
It even has rear tie-down points inside the cabin! And it’s a TurboDiesel, just like a PowerStroke F250, albeit with a little less power with 123hp@4,350 rpm and 184lb-ft of torque@2,400 rpm in its ultimate 1985 form from its 3.0 liter inline five. And although it weighs a bit under half the weight of the 2021 F250 PowerStroke TurboDiesel V8 at just 3,571 pounds (dare I say svelte?), it’s still a little shy in the overall power to weight ratio, but it is at least 36 years old so that’s a lot of progress that’s taken place in the meantime. And it’s the short wheelbase so not quite the rear legroom of the King Ranch Crew Cab but probably just as comfortable and with better handling. If a little drafty from the rear, perhaps.
