This feels a bit difficult to explain, so I'll try like this.
Imagine a 1.5-story house with a truss roof.
The floor for the upper floor rests on the bottom chords of the trusses (and on equally high studs between each truss).
How is it best to handle the gable wall if you have the ability to adjust the length of the house exactly as you want?
1. The last truss is "inside" the gable wall, i.e., part of the gable peak.
- Then the floor can’t rest on its bottom chord, so what must be done... add an extra beam?
2. The last truss is just inside the wall's surface layer (we can also consider an internal cross-bracing with 45x45, as that's my plan).
- Then maybe the floor can rest on the truss, depending on how you do it... or?
- But at the same time, it's quite a distance from where the sheathing is nailed to the last truss out to the eave, but perhaps you can handle that with an additional supporting stud, just inside the outer panel?
Yes, what do you wise ones say here?
Where would, just you, place the last truss on the house if you didn’t have to consider anything else?
And how would the upper floor's floor and the roof's sheathing be applied in relation to this?
I hope this was understandable, I thought about drawing some pictures, but that felt so tedious...
. Ask if it wasn't clear.

The simplest way is to use the same dimensions as the other trusses (to avoid problems with insulation and the ceiling, etc.). A few extra studs against the ridge beam, and it's fine to use ungraded timber even there...
