Ok guys need your help!

Well yea sure why not lol
The land beside me was grandfathers and when he passed away it went to my father. The house and land has been empty for 12 years I maintain it keep it mowed, pay the power keep it heated pay the taxes on the land etc. I use the house part for a work shop and my tools. I use the car port part for my car. Well my dad is a giant pos tool and we got into a disagreement over something not related and his comeback was that I take advantage of him and he wanted me to move stuff or he was having it towed. So I had to move all my stuff I didnt get it all today but I got most of the important expensive stuff.
Now I have to buy a shed or something.
I'm looking at some land I'm gonna buy and just get the heck away from here. The irony of it all is that everything he has was giving to him by my grandfather and I have never got a penny from the man since I was 17 years old when I moved out but I'm taking advantage of him???
I could trade Dirtbag father stories with you all day long but the good thing is is will never be like that with our kids...
My dad has been sober for 30 years and I still have to treat him like a seven-year-old. Or at least process what he says as if he was seven. Keeping at least a thousand miles away has helped..
