Anyone in the CT area done a pole barn?

I've been checking out the DIY kits and am mainly looking for construction equip storage gravel floor etc, but would like the option to finish interior ip later if needed.
Engineered columns (perm or direct bury 6x6) ?
I plywood sheathing on the roof then metal or just truss to metal?
Totally new to pole barns so any input is helpful. Trying to keep cost low though.
Thanks in advance for any info.
