The sleeping area is 64" X 80", so you should be fine - especially if you're able to sleep diagonally. For the dinette/couch conversion setup, I'd recommend swinging by and seeing it in person to get a real feel for it. Hope that helps!
Sorry, no on both. You would need to bring portable devices, or, step up to a larger teardrop trailer that has the space to house those components. Thanks for watching!
