I think what some are missing on the minimalist lifestyle is that it is not depriving yourself or living bare bones. To full time, I most definitely say a slide is a "needed" item. I would not want to see the OP get into something that would not bring the enjoyment that they are looking for. You do need room to move past the other person.
My cousin changes MHs like some folks change their socks. He's now to a 45' monster - it's gorgeous, but a monster. They can't get into much besides a KOA. His wife is miserable with it. Sitting in our wonderful little 26' one weekend, DH pondered, "what the H*** do they with need 45' for 2 people?". The answer is he has issues and no, he's not happy, but he's got the biggest and the best. She wants to go back to the days when they had an Outback and a P/U.
Suggest folks wondering about Minimalism do some reading and thinking how it might work for you....or not. In our case, it definitely works, just taking longer to get there than we'd like, but we're working toward that day. Kindle/Free or maybe $1.99.
