This has got nothing to do with my system, but a curiosity as it could have been an option early on.
Would you ever consider/allow a off-set into a trunk 5' or so out from the AH?
If we would have made a 6" short side offset (drop down, go 3', then back up) into the 8x20 trunk, we could have avoided some structure re-work.
It would have allowed the trunk to fit around a girder (headered off two joist bay's), and several take-offs could have been located between the "drop and raise" in the trunk, and run under the floor joist to registers.
Seems a 6" offset over 3-4' is not that drastic. I am assuming in the real world it must be, considering the big time hassle we are going through to avoid doing it.
Any comments about such a scenario?
