How practical is the sliding bunk over cab in Class A's?

Are there any families here who use the kind of sliding-down bunk over the cab in a Class A, who would care to share their experience with it? I'm curious how effective they are. Wondering if they're a pain to put up and down, blow up the mattress every day, pull out blankets and pillows, etc. On vacation, we drive nearly every day, plus the kids take naps, so this will be a more than once daily process.

We have always rented a Class C with the nice permanent bunk over the bed, which is perfect for the kids. So that's what we're shopping for. I've seen more recent model A's with that sliding bunk, and now getting to thinking that it might be a good option.

This weekend, I'm hoping to test drive the Thor Hurricane 32a I mentioned in another thread, which has that kind of bunk.
