I live on a 35ft boat. Built in 1998, I paid £18,000 for it 3 years ago. It has a fixed double, kitchen with 2 ring cooker, oven and grill. Small gas fridge. Shower and cassette toilet. A wardrobe that's small but me being a bloke, it's big enough. Plenty of storage under the bed and under the seating in the lounge. Ideally I'd have another area for eating as that all goes on in my living room, on the fixed table I have there. Other than that though, it's perfectly livable, providing that you get rid of most of your 'stuff', that being things you have but don't really need.
