Is the frame of the PD4106 steel or aluminum?

Wonder if some aircraft are considered monocoupe? And I'm not even thinking wing here just fuselage.

Most are I believe - it's a design far more common in the skies than on the roads.

My guess is that many of the engineers working on our earlier buses were former military men & women that were involved in the creation of the fleets of planes used during WWII. That experience translated directly to the construction used on our buses. Most planes during that era were monocoque, which apparently translates literally as 'single shell'.

Here's a breakdown of the terms used to describe the various types of vehicle construction: https://www.motortrend.com/news/body-on-frame-vs-unibody-vs-monocoque-what-is-the-difference/

Reviewing the link Richard posted, earlier mention of our Jeep Cherokee toad being Monocoupe is incorrect as it is more accurately unibody. FWIW
As far as the relation between military (WW2) machines & our vintage aluminum buses - TOO COOL... - on not just the bodies but also the power plants...

One of the first monocoque aircraft was the Aircoupe which was an early metal skinned low wing 2 seater but even with those you have metal ribs inside.

Exoskeleton means literally the skeleton is on the outside. Not really the right word for a perimeter skeleton that is on the inside.
