My layout is very similar TSBH. My kids had outgrown our old bunkhouse that did not have the slide. We LOVE having the outdoor fridge. That has saved more traffic in the camper than the bathroom door. I would go with the Triple slide. My kids are 13, 10, and 8. When we got the old bunkhouse, my kids were 8, 5, & 3. It was awesome when we first got it. We lasted 4-5 years in it. THen my kids had outgrown the bunkhouse- they didn't have enough storage and they were bringing friends camping the last few years. Kids grow FAST! LOL. One thing I like about our new layout is the bathroom- much nicer shower! THis layout will serve us the next 5 years and then we will re-evaluate. Good luck to you.
