JFan3....first off, Welcome to Garage Journal, secondly, you **** and I'm jealous
Thirdly....You **** on Garage Journal is a GOOD thing. Fourth....Fantastic looking building, and I'm jealous. Fifth....I jealous.
Now with that out of the road.....If it were mine, and this is only MY opinion, I would go with corrugated tin partway up as a wainscoting, then go with drywall above. But when it comes to finishing off the interior of a building, you get as many different opinions as women have shoes. You have drywall, OSB, drywall AND OSB, all OSB, all Drywall, plywood, plywood and tin, all tin, and any other multitude of combinations.
I would though, and others will probably agree.....leave the post exposed. Even if they are laminated post, cover them with some other wood to make them look like one solid post, and do all of the finishing in between. The interior choice you choose is all dependent on what you do in there, and what you like. It's a personal choice, just like commando, boxers, or briefs.
No one way is going to be better than the other except for what your intentions are. If you are the type that really gets pissed, and flies off the handle and throws large wrenches, then I would recommend a really thick OSB.
But the place looks fantastic. Make it for what YOU want. The only thing I can recommend is go to the Gallery and look at interiors of others garages and pole buildings, OR.......go to
www.houzz.com and type in a search for say "Pole barn interiors". But I have to warn you....once on Houzz, you'll be spending quite a bit of time on there also, and DO NOT, and I repeat, DO NOT let the wife be looking over your shoulder, or you'll be into so much work you'll never get done as they have a shitload of ideas for everything.
Once you get the interior that you decide, your next question will be....what color should I paint it, or what color of stripe to put in it, how high should I put the stripe. Again.....go to the GJ Gallery and look through the pics as everyone has a different idea that suits their own taste but will tell you that what they have is the latest and greatest. Again....it up to you and your taste, and we can only tell you what's best, as you clearly don't have a clue or you wouldn't be asking.
Seriously though....it looks fantastic, and I hope you hang around and become a long term member. You won't find a better group of people on any other websites.
And be sure to post up your progress pics and ideas. We all love to join in on the ideas, and really love pics. And the more pics the better as it will save the next one that comes along and ask.......what should I do.
BTW....what part of Ohio are you from? The reason I ask is that there are a lot of members from Ohio, and a group of us all like to hook up and get together at swap meets or car shows, and you're more than welcome to join. And there is a very large amount of members from northern Ohio. So many in fact that I think they are tipping the world a little bit so us ones down towards the middle and southern part of Ohio have to suffer their cold weather.
And you no doubt have members very close to you.
