First, happy new year to all.
I'm in the middle of doing a kitchen remodel, and due to the location I've chosen for the sink, which will sit under a window, which is on an exterior wall, I won't be able to simply extend the trap arm in the wall, due to the location of the studs that support the window header. (see picture).
My plan is to run the trap arm flush in front of the studs/drywall, inside the cabinet, it would run about 4-5 feet, within code, for a 2" pipe. At this point it would turn back into the wall to connect to a vertical revent/drain. The revent would be 1 1/2", and the drain itsef would be 2". Would I affect the trap in anyway, based on the length of the trap arm, and/or the turn I would have to make back into the wall to connect to the vertical pipe? Once I'm connected back into the wall the vent itself would attach to an another vent stack, which, in turn connects to a horizontal vent branch one floor above, and eventually, to the main stack, and out the roof. The drain would need to go about 10 feet to connect to another 2" drain which in turn connects to the main soil stack in the basement. (see picture).
I posted most of the questions in the picture attached, but in essense:
1) Is the design sound?
2) The type of fittings I would need at the various junction points in the vent and drain sections?
3) Is the sizing for the drain/vents correct?
4) The length of the vents and drains, is this within appropriate limits based on the design.
5) Are there any minimum height requirements on the venting that I need to follow?

I also, in the process of coming up with the above questions, found this site:
Trap arm - learn about dirty arms with this plumbing diagram.
which details what I'm proposing on doing (a dirty drain rough-in), vs a standard rough-in. Can anyone tell me the advantages/disadvantages of using either of these designs?
In particular I don't have too much space below the window, and based on what I've been reading a standard rough-in requires a certain amount of space above the flood level of the sink for it to work. Is this correct?
