I’m not sure what information you’re really after, but to your original question of “curb-to-curb”, the way I’ve seen it measured by manufacturers, the vehicle length nor the body width influence that measurement.

Think of it as going to an empty parking lot, turning the steering all the way, and then drive a big circle. What determines the size of the circle (at curb level) are the wheelbase, and also the front wheel cut. Extra vehicle body width nor extra rear overhang affects the curb-to-curb measurement. Extra length at rear always falls inside circle.

Sometimes we see a wall-to-wall dimension which is affected by front overhang and also body width, but this format is less common because chassis manufacturers don’t know what final body builder will manufacture on their chassis.


Regarding your first post, I imagine the shorter RV you mentioned may be built on an F-53 chassis, which I believe has a greater wheel cut than the E-Series. That combined with shorter wheelbase should have a tighter curb-to-curb dimension.
