I am playing around with designing a truck camper with overhanging/cabover sleeping area/bed (picture).
The sleeping area/bed will be supported by 3 2x4s.
Now I need to figure out the best design and if they are actually feasible.
Design 1:
All 3 2x4 are cantilevers resting on 2x4 coming up from the bottom.

Design 2:
The middle 2x4 is a cantilevers resting on 2x4 coming up from the bottom.
The 2x4 on the sides are longer and resting on 2 2x4s

The dimensions
The cantilevers are 72" long. For Design 2 I will have an extra of 36" coming to the 2nd 2x4.
The weight on the 3 bars will be around 440lbl. This excludes any movement which might add stress to the structure.
The questions
- Is this feasible at all?
- Can any of the 2 designs carry the weight?
- If possible could I come by with 2x2 to save weight?
Also I would greatly appreciate any reading material on how I can calculating this.
