>>1936449For hollowtech II shimano, the 73mm cups are each 2.5mm narrower than the 68mm cups.
So a 68mm road frame with an ultegra bottom bracket is essentially the same as a 73mm mtb frame with a deore bottom bracket and both of them will take the same hollowtech II cranks, road, or mtb.
There's no compatibility issue for you there.
The 73mm mtb bbs are even sold as 68/73 with included 2.5mm spacers, so that you can use them in road frames.
As a side note, that ability to space mtb bbs in road frames can be very useful, especially with square taper, for installing cranks designed for asymmetrical bottom brackets (which are no longer readily available).
I have measured this as well and found that one shimano bottom bracket I had (of many) did not conform to this, so as another aside i'll say that this is theoretically how it works, but trial and error, measurement, basic understanding of how the systems can and should work and common sense need still be applied to bottom bracket installs.

>>1936449>Panorama AnticostiLooks quite good. Has decent fork bosses which is the common drawback on grabel frames. Can't say i like the mustard colour.
Kona Sutra too is a heavy duty touring bike. I'd say it fits a similiar niche as the long haul trucker, I wouldn't advise someone get one unless serious touring is really the primary purpose, otherwise it's just an overly stiff, heavy, sluggish overbuilt bike, Consider you can still tour on something sportier.
I wouldn't worry about the rust issue. I also wouldn't necessarily worry about getting steel. Consider generic endurance road bikes with wider tire clearance. Those are the best bang for buck allrounders.
I don't know exactly what you're gonna be doing but you can chuck 35mm G-Ones on most entry level disc road bikes now, the gearing has a 1:1 low which can be upgraded with a subcompact, and then you lean into bikepacking bags. For an unloaded bike your ride ends up lighter and cheaper
