Anyone paint their plywood interior?

In the planning stages I was all about the beadboard, but ultimately it weighs a lot, adds cost, and I'm not trying to build a luxury lodge, I'm trying to build a dry, comfortable place to camp with a real bed and climate control and haul some stuff with me.
So why not just paint it?
I don't know off the top of my head if I've seen pics in build threads of people who have painted their plywood. Anyone done it? Got any tips or pics?
Thanks for looking.
