me again....I have the exact same issue. But I've already done a pergo floor. there's no need for a "sub floor"...i.e. second layer of plywood on top of the plywood that airstream installed. you can pergo right on top of it. One great thing about the pergo "floating floor" is that it can be removed should you ever suspect a leak in the future...then it can be put right back in place, without damage. ANYway...take a look at my photo album for pics. my trailer is laid out just like yours, at least in the bath area. I just ran the pergo right in there.
