And the ability to " drop & roll " when ya slip & fall off exiting a cab over for a smooth landing .Yeah a guy's gotta be in relatively good shape to even get up there.
I'm the same way , even with the oxygen cap welded to the wheel hub to provide another step .I remember the late 70s Freightliners had what we called "fatboy bars" to climb up into the cab. No matter what you did, you always ended up with the wrong foot first when you got up there.
That or a giant Toyota Stout.The truck in the top pic appears to be designed by a committee located in several different countries. Actually it looks to be mostly Russian. But... Is it just my imagination, or are those front fenders from a mid 60's Ford heavy duty gasser?
