We have a 2013nSalem 30kqbss and the interior is almost identical to the Wildwood. We really like ours, and aside from some minor problems, it's been a great unit thus far. We just got back today from our longest camping trip in it (8 nights) and never did we feel cramped or uncomfortable. It's just 3 of us, but it's perfect. My daughter loves the back bedroom.
We haven't done much in the way of modifications yet, but we will. We're still getting a feel for it, and then we'll decide what we want to change.
Good luck with yours!
