 I was looking at this picture and I don't see what holds the overhang up.

Most all of the weight is to the back on a truck camper all your tanks, fridg, bath, dinet, don't need anything to hold front up. When camper is off the truck make sure the front is a little higher than the rear. Camper will wobble around a lot but is safe. We take camper off truck all the time never had any worries of front not being supported.Just make sure you have some small levels on your camper at the rear both sides as you raise the camper its very important you keep the camper level with the front just slightly higher.

I think OP is talking about what prevents the overhang from falling off, or bending down from the rear compartment of the RV.

 

from your picture, it appears that the stud that is on front of rear compartment is HD compared to rest.

than you have a triangle based on strut that goes forward and downwards from this HD stud and is attached to "bottom plate" frame rail for cab-over

than you have heavy "top plate" frame rail which also is supported with a triangle that goes forward and upwards to this top plate.

plus the construction is designed so the whole wall acts like "one structure" where each piece is secured together and is part of the overall support structure.

Look at the triangular bracing.  Think bridge.  The vertical beam at the front wall of a TC is one of the strongest frame elements in the whole TC.  The big frame part that extends from the rear of the camper all the way to the front of the overhead is a cantilevered beam, also very strong.

We've all heard Snowriver made the first TC with a slide, it would be interesting to know who built the first one with the bed overhang, and how they figured out how to support it.
I have been a tent camper since my Boy Scout days long, long, ago. Now I need to get up off of the cold ground to get a good nights rest, a truck camper seems to be the best choice. I am here to learn as much as I can.

Classically, the top header carries the majority of the load from the cab-over, transferring it into the verticals and the truss cross pieces.   In classic built units, this was generally a 2x6 running the length of the rig.
