The garage is not attached.

I ripped the side wall apart this weekend.
From the inside out, studs, 12" wide tongue and groove at 45 degree
angle, tar paper then red brick.
All of the wood looks good, the paneling and insulation was from the
60's - it is all going in the trash.

I am now planing on drywall everywhere.
Any benefit to using the moisture type drywall in bathrooms? Or just
go with standard 5/8" and a good coat of paint.
I will be adding a furnace and correcting ventilation issues.
I have a new ridge vent in the roof, but little soffit vents, that
look to be clogged with insulation.
This will hopefully fix my moisture issues.
