well sounds like you have a good base plan
as I was eading this, I kept thinking, where I used to stay in Ohio, all the cabins in the area were all Amich build's and the prices were super reasonable, made me wish they were closert o me here in PA<> I would have had them build me one here L
and was going to suggest you try to contact them and see if they would build you one LOL
so you beat me tyo that idea, buy finding one pre built
looks like a nice cabin too
and my advice to you on your new lands would be to post the crap out of it where it borderes the public lands,
like a sign every 20+ ft, but the aluminum sigh's they last 20+ yrs, and can be had pre signed too

as hard work on building a great hunting spot, don't leave anyone the chance of saying they didn't know it was private
I get that excuss here all the time and I even have it posted like crazy!
but have to think it stops some!, and Ohio, the sate will help you, unlike here in PA
and last, how about a pic of that buck you killed?? sounds like a dandy of a buck!
best of luck on it all!
