I envision moving around a lot. Like a month in one place, bicycling around, seeing the sights, then moving on to somewhere new. I am currently single, and if I'm honest, I'd be very surprised if I wasn't single when I retire. LOL Maybe a dog. I feel like I'd be fine in a 30' RV. I have an 1,800' sq ft home right now, and I spend almost all my time in the bedroom, the bathroom, the kitchen, and my "man cave" (call it 12x16 sq ft). My hobbies (aside from kayaking) doesn't require much gear. Photography, a drone, hiking (day hikes mostly).
